Makefile:5: recipe for target 'install' failed

[vbmade2000]

I am trying to build gi.
Steps I followed:

$ go get -t -u -v github.com/gijit/gi/...
$ cd $GOPATH/src/github.com/gijit/gi && make

I am getting

Makefile:5: recipe for target 'install' failed

Following are logs of make

@vbmade2000 Hey! Sorry for the delay in replying. Github didn't ping me, strangely. Feel free to gmail me directly if you need assistance or file a new issue.

The transcript doesn't tell me why go build failed. Can you run cd $GOPATH/src/github.com/gijit/gi/cmd/gi; go build manually to see what the problem was?

If that doesn't let you fix it immediately, try go build -x which will tell you the exact commands the compile and link is trying. If you still have issues, post the output of the go build -x.

[glycerine]

Also, what operating system are you building on?

[vbmade2000]

Sure. The OS is Ubuntu 17.

[glycerine]

Sure. The OS is Ubuntu 17.

Perfect. This should work. I just verified on a linux box I have, and it built. Though it was centos7.3.

What does go build -x, when run in the cmd/gi subdirectory, say?

[glycerine]

Ah. luajit wasn't being installed, only built. So then asking luajit for its version failed. I pushed a fix for this just now, in v0.6.3, so that we really don't require installation of luajit--so that users won't have any existing luajit overwritten with our version. git pull origin master --tags and then try again.

For developing, you will definitely want to install LuaJIT. So just cd $GOPATH/src/github.com/gijit/gi/vendor/github.com/LuaJIT/LuaJIT/src and then make install or sudo make install if need be.

[vbmade2000]

Correct. luajit was not being installed. It was being built only. I manually copied it to $PATH and then tried building but still failed.

Now I am going to build gi again after pulling latest changes.

[vbmade2000]

Tried building after pulling latest changes but still facing same issue. Following is an output of go build -x.

So you can follow along, here are the details:

This is a link command that is failing:

gcc -I . -fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=$WORK=/tmp/go-build -gno-record-gcc-switches -o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/_cgo_.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/_cgo_main.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/_cgo_export.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/golua.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/lauxlib.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/lua.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/lua_defs.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/c-golua.o -g -O2 -lm -ldl ./../../../LuaJIT/LuaJIT/src/libluajit.a ./../../../LuaJIT/LuaJIT/src/libluajit.a

The libraries libm.so (the math library) and libdl.so (the dynamic loading library) are linked in with the -lm and -ldl flags, towards the very end of the line.

However, the linker cannot locate those libraries on your system. That's what is meant by "undefined reference". The header files where there, just fine, to compile against. But when it came time to link against the actual libraries, the dynamic linker couldn't find them.

That's what this lines means:

# github.com/gijit/gi/vendor/github.com/glycerine/golua/lua
../../vendor/github.com/glycerine/golua/lua/../../../LuaJIT/LuaJIT/src/libluajit.a(lj_clib.o): In function `lj_clib_index':
lj_clib.c:(.text+0x183): undefined reference to `dlsym'

The above line refers to a dl function, in the library for dynamically loading binary code into a running process.

../../vendor/github.com/glycerine/golua/lua/../../../LuaJIT/LuaJIT/src/libluajit.a(lib_math.o): In function `lj_ffh_math_log':
lib_math.c:(.text+0xe2): undefined reference to `log2'

The above errors and the others about pow tell us that the math library couldn't be located by the linker.

Now both these libraries probably exist on your system. It's just a small matter of telling the linker where to find them.

This is typically controlled on a linux system by the ld.so.conf file, somewhere in the /etc directory.

Step 1, locate the libraries:

$cd /
$find . -name 'libm.so' -print # note where it is found
$find . -name 'libdl.so' -print # ditto

Step 2

Then add directories to the ld.so.conf

Step 3
run ldconfig as root to pick up the changes.

Then try again.

[glycerine]

There is one other possibility, that the link line is out of order. Since go build is constructing it, I consider this unlikely. But you could test it by manually invoking the same link line and putting the -lm and -ldl flags toward the front of the command:

cd /home/vbmade2000/go/src/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua

gcc  -lm -ldl -I . -fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=$WORK=/tmp/go-build -gno-record-gcc-switches -o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/_cgo_.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/_cgo_main.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/_cgo_export.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/golua.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/lauxlib.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/lua.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/lua_defs.cgo2.o $WORK/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua/_obj/c-golua.o -g -O2 -lm -ldl ./../../../LuaJIT/LuaJIT/src/libluajit.a ./../../../LuaJIT/LuaJIT/src/libluajit.a

If that builds cleanly, then it was an order problem, the flags came in the wrong order.

[glycerine]

As you are adjusting the linker, a quick test would be to try and compile and link a small C program. This will give you an independent test that the linker is now working.

Make a test.c file:

#include <stdio.h>
#include <math.h>
int main(void)
{
  double x = 0.5;
  double result = sqrt(x);
  printf("The square root of %lf is %lf\n", x, result);
  return 0;
}

compile and link and run it

gcc test.c -o test -lm && ./test

If it doesn't find the math library (libm.so), then keep changing the ld.so.conf file until it does. Remember to run sudo ldconfig after each change, or the change may not take effect.

I grabbed a docker container from dockerhub of Ubuntu17, ubuntu:artful-20180112

It looks like /etc/ld.so.conf is right there in /etc. The libraries you need are in /lib/x86_64-linux-gnu.

root@cce186d9e685:/lib/x86_64-linux-gnu# ls -al|grep libdl

root@cce186d9e685:/lib/x86_64-linux-gnu# 

when I look at the ld.so.conf it points me to the /etc/ld.so.conf.d:

root@cce186d9e685:/etc/ld.so.conf.d# ls -al
total 16
drwxr-xr-x 2 root root 4096 Jan 12 22:58 .

# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
root@cce186d9e685:/etc/ld.so.conf.d# 

and I see that /lib/x86_64-linux-gnu is listed in this container by default. So unless the cache needed refreshing by running sudo ldconfig, I can't fathom what went wrong on your build box.

Let's get the test.c building, then we'll be on solid ground.

[glycerine]

Here's a link to installing gcc on Ubuntu.

https://gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91

If nothing else works, might try re-installing gcc per that gist.

[glycerine]

hmm... okay, I can reproduce the issue in the docker container. Troubleshooting it now.

[glycerine]

It is an order of flags issue. If I manually move the -lm and -ldl to the end of the link line, then it builds. Example:

me@dc7613b8de09:~/go/src/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua$ gcc -I .  -fPIC -m64 -pthread -fmessage-l\

T/LuaJIT/src/libluajit.a ./../../../LuaJIT/LuaJIT/src/libluajit.a -lm -ldl

versus the orignal that CGO is generating fails:

me@dc7613b8de09:~/go/src/github.com/gijit/gi/vendor/github.com/glycerine/golua/lua$ gcc -I .  -fPIC -m64 -pthread -fmessage-l\

./../../../LuaJIT/LuaJIT/src/libluajit.a(lj_clib.o): In function `lj_clib_index':
lj_clib.c:(.text+0x172): undefined reference to `dlsym'

So now to figure out how to make CGO put the -l flags at the end...

[glycerine]

I put in additional -lm -ldl flags in the CGO for golua, and that fixes the problem at tip.

PS I hate how Ubuntu changed the default linker options. It got super finicky and broke tons of stuff. Not such a great idea really. Background is here [1][2].

@vbmade2000 I'm glad you reported this, and I'm glad it was such an easy fix once the diagnosis was clear. Ubuntu users everywhere will be much happier.

[vbmade2000]

@glycerine It worked :). Thanks.
