cmake encounter error on mac #360

luckypoem · 2016-06-06T02:57:26Z

hi.
git clone https://github.com/libevent/libevent
cd libevent
mkdir build
cd build
cmake ..

it exports:
...
Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
system variable OPENSSL_ROOT_DIR (missing: OPENSSL_INCLUDE_DIR)
...

but actually previously i already installed openssl on mac successfully:
$ git clone https://github.com/openssl/openssl
$ cd openssl
yudeMacBook-Air:openssl brite$ export CPPFLAGS=-I/usr/local/cellar/openssl/include
yudeMacBook-Air:openssl brite$ export LDFLAGS=-L/usr/local/cellar/openssl/lib
yudeMacBook-Air:openssl brite$ ./config --prefix=/usr/local/cellar/openssl/
yudeMacBook-Air:openssl brite$ make
yudeMacBook-Air:openssl brite$ make install

so,how to fix the issue?

azat · 2016-06-07T10:30:05Z

@luckypoem can you dump env before cmake .. ?

errzey · 2016-06-13T18:05:33Z

Try out

brew upgrade openssl
brew link --force openssl
pkg-config --modversion openssl

errzey · 2016-06-18T00:21:19Z

Tested on OSX+brew, after uninstalling and reinstalling OpenSSL I got the same type of error:

CMake Error at /usr/local/Cellar/cmake/3.5.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the

  /usr/local/Cellar/cmake/3.5.2/share/cmake/Modules/FindOpenSSL.cmake:370 (find_package_handle_standard_args)
  CMakeLists.txt:670 (find_package)

After the above commands:

-- Found OpenSSL: /usr/local/Cellar/openssl/1.0.2h_1/lib/libssl.dylib;/usr/local/Cellar/openssl/1.0.2h_1/lib/libcrypto.dylib (found version "1.0.2h")

So that works. Mind if I close?

luckypoem · 2016-06-18T01:00:19Z

what commands are your " the above commands"?

errzey · 2016-06-19T21:47:05Z

#360 (comment)

lifejuggler · 2016-06-21T15:30:09Z

there are no commands in the #360 ... only messages. what commands did you use to make it work?

errzey · 2016-06-21T15:31:29Z

OK, again:

brew upgrade openssl
brew link --force openssl
pkg-config --modversion openssl

lifejuggler · 2016-06-21T15:36:46Z

That command doesn't seem to work...

Oh, 2.0. You can try out the OPENSSL_LIBADD env flag.

azat · 2016-10-02T23:28:28Z

@luckypoem / @lifejuggler any progress?

lifejuggler · 2016-10-03T19:49:09Z

adding the flag worked for me. I dunno about luckypoem

kerneljake · 2016-10-18T19:52:50Z

The following worked for me with 2.0.21-stable on El Capitan 10.11.6 :
$ CPPFLAGS=-I/opt/local/include ./configure --prefix=/opt/local
$ make

azat · 2016-10-18T22:30:03Z

Okay, I guess this can be closed.

nquoctuan · 2017-02-13T08:51:51Z

Hi guys,

I am quite new to this lib, can you give me more detail how to fix it by adding flag?

thanks,
Jimmy.

nquoctuan · 2017-02-13T08:54:00Z

I did follow @kerneljake , but i got errors below:

azat · 2017-02-13T21:53:05Z

@nquoctuan do you use brew?

AFAIR there are some changes with locations oh libs/headers (on 10.12 or so) so can you try something like this instead CPPFLAGS=-I/usr/local/opt/openssl

P.S. totally untested.

nquoctuan · 2017-02-14T10:27:32Z

Hi @azat ,

Yes, i try to build libevent for compiling thrift on macos.

Below is the result of brew info openssl

openssl: stable 1.0.2k (bottled) [keg-only]
SSL/TLS cryptography library
https://openssl.org/
/usr/local/Cellar/openssl/1.0.2k (1,696 files, 12M)
  Poured from bottle on 2017-02-13 at 17:42:51
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/openssl.rb
==> Dependencies
Build: makedepend ✘
==> Options
--universal
	Build a universal binary
--without-test
	Skip build-time tests (not recommended)
==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

Any ideas?
Thanks

azat · 2017-02-14T12:07:44Z

You can try next:

autotools

pass -I to the compiler

export CPPFLAGS=-I/usr/local/opt/openssl/include
export LDFLAGS=-L/usr/local/opt/openssl/lib
./configure
./make

let pkg-config take care

PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig ./configure && make

cmake

-DOPENSSL_ROOT=/usr/local/opt/openssl

And for now autotools is preferable build system.

nquoctuan · 2017-02-18T15:53:05Z

Thanks @azat , i will try it now.

songhao8080 · 2017-03-27T12:46:45Z

@nquoctuan can you fix it

Shunzi007 · 2018-02-02T16:21:49Z

I find the above solutions don't work for macos 10.13.3 now!
Could I add something in the CMakeList.txt or the build.sh

cmake -DCMAKE_TOOLCHAIN_FILE=./ios.cmake -DIOS_PLATFORM=OS -H. -BXcode -GXcode

azat · 2018-02-03T22:39:57Z

@Shunzi007 are you sure that openssl installed at /usr/local/opt/openssl (i.e. it contains lib/include and others) ?

Shunzi007 · 2018-02-04T13:05:40Z

@azat Yes, I am sure. if I run
cmake -H. -BXcode -GXcode -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2n -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2n/lib ..
it goes well in this repository.

However, in my project, in which libevent is a subdirectory, I run cmake command
cmake -DCMAKE_TOOLCHAIN_FILE=./ios.cmake -DIOS_PLATFORM=OS -H. -BXcode -GXcode -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2n -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2n/lib
will show the error

CMake Error at /usr/local/Cellar/cmake/3.10.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the

libevent/CMakeLists.txt:695 (find_package)

so I wonder whether could I add some line into the CMakeList.txt.
Thank you.

azat · 2018-02-04T13:44:54Z

@Shunzi007 I don't think that the problem is in libevent's cmake rules, could you post output of cmake --trace .... ?

(upd: better upload it to some pastebin and post the link here)

Shunzi007 · 2018-02-04T16:13:30Z

do cmake -DOPENSSL_ROOT=/usr/local/opt/openssl .. in libenvent/build could get(https://gist.github.com/Shunzi007/7a45b4d848317eedd1e5b252aced43c8)
so your reply on 14 Feb 2017

You can try next:

autotools
pass -I to the compiler
export CPPFLAGS=-I/usr/local/opt/openssl/include
export LDFLAGS=-L/usr/local/opt/openssl/lib
./configure
./make
let pkg-config take care
PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig ./configure && make
cmake
-DOPENSSL_ROOT=/usr/local/opt/openssl
And for now autotools is preferable build system.

the last suggestion goes wrong now?

cmake -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2n -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2n/lib .. goes well.

azat · 2018-02-04T16:31:02Z

I'm not sure that I understand you @Shunzi007
If I understand you correctly then cmake from the root directory of the libevent works, but not from subdirectory.

Could you post the full (by full I mean run of cmake without any cache, i.e. from the clean/new build directory) output of (with --trace):

cmake -DCMAKE_TOOLCHAIN_FILE=./ios.cmake -DIOS_PLATFORM=OS -H. -BXcode -GXcode -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2n -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2n/lib --trace # from subdir
cmake -H. -BXcode -GXcode -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2n -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2n/lib .. --trace # from the root dir of libevent

Without this I cannot help you, since I don't know any details.

Shunzi007 · 2018-02-04T16:45:42Z

@azat cmake -DCMAKE_TOOLCHAIN_FILE=./ios.cmake -DIOS_PLATFORM=OS -H. -BXcode -GXcode -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2n -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2n/lib --trace
from subdir
(https://gist.github.com/Shunzi007/056690f845718b92e332b993d2d06054)
Thank you very much.

azat · 2018-02-04T17:18:11Z

Just like I though, looks like OPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2n/include and it does not contains openssl/ssl.h and/or openssl/opensslv.h

Post the output of find /usr/local/Cellar/openssl/1.0.2n/ into gist please.

BTW if you installed openssl correctly then you don't have to set OPENSSL_LIBRARIES (it will be installed by find_package(OpenSSL))

Shunzi007 · 2018-02-05T02:14:52Z

find /usr/local/Cellar/openssl/1.0.2n/
(https://gist.github.com/Shunzi007/12d4600c8d5b59fb7f1057d2f896136c)

ploxiln · 2018-02-05T04:02:55Z

I see references to "ios", is this for iPhone / iPad? Which are ARMv8 architecture? The x86_64 openssl built by homebrew won't work for that.

ploxiln · 2018-02-05T04:10:00Z

/Users/wangshun/Code/ios-cmake/ios.cmake(75):  set(IOS_PLATFORM_LOCATION iPhoneOS.platform )
/Users/wangshun/Code/ios-cmake/ios.cmake(78):  set(CMAKE_XCODE_EFFECTIVE_PLATFORMS -iphoneos )
...
/Users/wangshun/Code/ios-cmake/ios.cmake(127): set(IOS_ARCH armv7 armv7s arm64 )

Looks like.

Shunzi007 · 2018-02-05T06:19:49Z

@ploxiln Yes, it is an iOS app. I want to start a server in it. so I need to build a arm64 openssl for it? I will have a try.

azat · 2018-02-05T11:51:33Z

Yeah, but this will explains why it will not link with them, but not the fact that it cannot find it, it cannot detect even the version from the header, even though it exists.

Obviously, I'm missing something here..

azat · 2018-02-05T12:01:20Z

And the reason this is CMAKE_FIND_ROOT_PATH

/Users/wangshun/Code/ios-cmake/ios.cmake(137):  set(CMAKE_FIND_ROOT_PATH ${CMAKE_IOS_DEVELOPER_ROOT} ${CMAKE_IOS_SDK_ROOT} ${CMAKE_PREFIX_PATH} CACHE string iOS find search path root )

Since CMAKE_FIND_ROOT_PATH will be prepended for every find_*() according to cross compiling doc

Shunzi007 · 2018-02-06T07:07:28Z

@azat Yes, I think the main problem is cmake can not find openssl. I have tried with (https://github.com/x2on/OpenSSL-for-iPhone) to get openssl for iOS, and then use cmake -H. -BXcode -GXcode -DOPENSSL_ROOT_DIR=/Users/h172462/Code/OpenSSL-for-iPhone/bin/iPhoneOS11.2-arm64.sdk -DOPENSSL_LIBRARIES=/Users/h172462/Code/OpenSSL-for-iPhone/bin/iPhoneOS11.2-arm64.sdk/lib, but it still tells the error.
As I am a new hand of cmake, could you give me some suggestion ?
Or I wonder if could I disable openssl to just pass build?

Shunzi007 · 2018-02-06T09:30:21Z

Hi guys, I have found a way to fix the cmake issue, I just add library and include path and the command now is
cmake -DCMAKE_TOOLCHAIN_FILE=./ios.cmake -DIOS_PLATFORM=OS -H. -BXcode -GXcode -DOPENSSL_SSL_LIBRARY=/Users/h172462/Code/OpenSSL-for-iPhone/lib/libssl.a -DOPENSSL_CRYPTO_LIBRARY=/Users/h172462/Code/OpenSSL-for-iPhone/lib/libcrypto.a -DOPENSSL_INCLUDE_DIR=/Users/h172462/Code/OpenSSL-for-iPhone/include
openssl is working now.

azat · 2018-02-06T10:24:01Z

This is an option, but not a good thing to do, you should base your openssl location against your CMAKE_FIND_ROOT_PATH and pass only OPENSSL_ROOT_DIR (that should be in inside your CMAKE_FIND_ROOT_PATH).

Please read the cross compiling doc from #360 (comment)

And to turn off openssl you could add -DEVENT__DISABLE_OPENSSL=ON

Shunzi007 · 2018-02-07T08:27:13Z

@azat Hi, the project still has build errors, I need your help.
use cmake 3.10.2 macOS 10.13 and Xcode 9.2
the step is

git clone https://github.com/libevent/libevent.git
cd libevent
curl https://gist.githubusercontent.com/Shunzi007/6fb7fb8f779fc6034e3196d74b22df01/raw/280f7ca20204c8c1d9013ac47da91fae5183e3b2/ios.cmake > ios.cmake
git clone https://github.com/x2on/OpenSSL-for-iPhone
cd OpenSSL-for-iPhone && ./build-libssl.sh --version=1.0.2n
cd ..
cmake -DCMAKE_TOOLCHAIN_FILE=./ios.cmake -DIOS_PLATFORM=OS -H. -BXcode -GXcode -DOPENSSL_SSL_LIBRARY=./OpenSSL-for-iPhone/lib/libssl.a -DOPENSSL_CRYPTO_LIBRARY=./OpenSSL-for-iPhone/lib/libcrypto.a -DOPENSSL_INCLUDE_DIR=./OpenSSL-for-iPhone/include -DEVENT__DISABLE_THREAD_SUPPORT=ON -DIOS_TARGET:STRING=8.0 -DCMAKE_BUILD_TYPE=Debug

Here is the result (https://gist.github.com/Shunzi007/423ec8d0604cb35f1d0263613e20fca6)
It builds succeed, but tells errors when opened by Xcode.

Could you have a try and help me fix these?

azat · 2018-02-07T09:49:11Z

I guess it just cannot find path to headers, that created by cmake, particularly:

include/evconfig-private.h
include/event2/event-config.h

And I don't know how xcode doing this, so you have to figure this out by yourself.
