I get a PSOL error....

adding module in ../incubator-pagespeed-ngx/
ngx_pagespeed: pagespeed optimization library not found:
./configure: 33: ../incubator-pagespeed-ngx//config: [[: not found
basename: extra operand 'release'
Try 'basename --help' for more information.

  You need to separately download the pagespeed library:
     $ cd ../incubator-pagespeed-ngx/
     $ wget In a release this file would contain the URL to download the pre-compiled PSOL
binary, but on development branches (like this one) you have to build PSOL from
source yourself.  See:
  https://github.com/apache/incubator-pagespeed-ngx/wiki/Building-PSOL-From-Source
     $ tar -xzvf  # expands to psol/

  Or see the installation instructions:
     https://developers.google.com/speed/pagespeed/module/build_ngx_pagespeed_from_source

And when i download the package with a PSOL folder i still get a PSOL error.... I don't get what is wrong.....

[eilandert]

./configure: 33: ../incubator-pagespeed-ngx//config: [[: not found

First thing that comes to mind is that [[ is a bash command, are you running in sh or another shell?

[Lofesa]

The PSOL folder must be a sub-folder where you have pagespeed.
Example. you download the incubator-pagespeed-ngx-1.14.36.1-beta.tar.gz and untar it, then you have a folder incubator-pagespeed-ngx-1.14.36.1-beta/.
Next, you go to these folder (cd /path/to/the/folder/incubator-pagespeed-ngx-1.14.36.1-beta/ ) then download the psol library and untar it.
Now you have some like incubator-pagespeed-ngx-1.14.36.1-beta/psol/lib/Release/linux/x64/pagespeed_automatic.a

Or maybe you need these steps: https://groups.google.com/g/ngx-pagespeed-discuss/c/PSrbZrjKpKI/m/TtE59WSfAwAJ

I have same issue with nginx 1.20 with fedora server 34 ngx_pagespeed-release-1.13.35.2.
Psol directory is exist, but still failing to detect. Seems like config file issue
Attempt build RPM with mockbuild

The question why you need ask interactive question in middle of config file ?

adding module in /builddir/build/BUILD/nginx-1.20.2/ngx_pagespeed-release-1.13.35.2

You have set --with-debug for building nginx, but precompiled Debug binaries for
PSOL, which ngx_pagespeed depends on, aren't available.  If you're trying to
debug PSOL you need to build it from source.  If you just want to run nginx with
debug-level logging you can use the Release binaries.

**Use the available Release binaries?**

But under lib there are others folders (/lib/Release/linux/x64/pagespeed_automatic.a)
Maybe the download from https://dl.google.com/dl/page-speed/psol/ fails.
I don´t know if these repository is working
For never version you can find it at https://dist.apache.org/repos/dist/release/incubator/pagespeed/1.14.36.1/x64/
Maybe you can use the nginx module 1.13.35.2. with this latest psol

[volga629-1]

But why need download if full library folder exist ?

<mock-chroot> sh-5.1# cd modsecurity-nginx-v1.0.1/
<mock-chroot> sh-5.1# cd ../ngx_pagespeed-release-1.13.35.2
<mock-chroot> sh-5.1# find . -name pagespeed_automatic.a
./psol/lib/Release/linux/x64/pagespeed_automatic.a
<mock-chroot> sh-5.1# 

[Lofesa]

I´m asking because in the script install the psol is downloaded from a google site and some times this download fail, since the module don´t be a google proyect. So maybe the folders are in place, but not the file..
I never used to install from scripts, do the manual way.
Download the ngx_pagespeed, uncompress, go to the directory, download the psol and uncompress it, then delete the downloaded psol compressed file, and create a tar.gz, donwload the nginx sources, put the create tar.gz ib sources and modify the nginx.spec and do rpmbuild. When asked, put Y to use the psol library in pakage and get the rpm package

[jmarantz]

I think we might need to update https://www.modpagespeed.com/doc/build_ngx_pagespeed_from_source to point to a download page under Apache rather than https://dl.google.com/dl/page-speed/psol/${NPS_RELEASE_NUMBER}.tar.gz -- Otto what was your thinking about this?

[oschaaf]

@jmarantz that makes sense, I'll look into that.

With some fiddling this produces an nginx binary for me:

#!/bin/bash

Notes:

• During the release process, I didn't go ahead and release ngx_pagespeed along with mod_pagespeed. This is because that would need ngx_pagespeed to go through some more compliance checking to ensure it is on par with ASF standards.
• I did however go as far as tagging a release candidate. Unfortunately I made a typo (1.14.33.1-RC1 ought to have been 1.14.36.1-RC1). This is what we use above.
  I think it would be OK for us to update the documentation with a script similar to what I am posting here, as long as we add a disclaimer/warning about this being a WIP from an ASF policy PoV.

According to this, I still fail to build on Alpine 3.15 (alpine:3.15).

I already install [libuuid] and [util-linux-dev] (contains uuid/uuid.h and libuuid.so) and other depends.

The compilation parameters use the parameters of the nginx official alpine container.

Please help me check it. What's wrong with it?

[tomazurro]

the build error in your case is caused by the undefined references, which in turn are caused by an outdated build environment. I had the very same error with default gcc-Version 4.8.5 on centos 7 and solved it by updating to version 7+ using slc:

yum -y install centos-release-scl
yum -y install devtoolset-7-gcc* devtoolset-7-binutils
scl enable devtoolset-7 bash
gcc -v
[resp. your build command]
