[Architecture] OLS compilation for ARM

[wiz64]

Hello guys,
Me and my friend really need to host a few sites on Raspberry Pis with Ubuntu 20.04 focal aarch64 (ARM)
OLS isn't available pre-compiled, but it can be compiled for ARM
Previous issues regarding the same are outdated. We are looking for ARM version of OLS.
Please provide us instructions to compile for ARM and if possible, a pre compiled binary that should work with it.

You can try run build.sh in a ARM linux server. see how it goes.
May need a little more powerful server than Raspberry Pis, as it need to compile all the dependency libraries.

@litespeedtech can you take a look what went wrong? First time everything compiled perfect but I didn't document what I did and destroyed everything.

My build config: Qemu 4 vcpu, 4GB ram, Virt 5.8, Almalinux 8.4 aarch64

Please try the latest v1_7 branch, some old code cleaning up. It should take care of this compiling error.

[litespeedtech]

Release 1.7.12 should have addressed this.

[istiak101]

Sorry for being late, forgot about this. Just wanted to mention lsquic/src/lshpack wasn't copied to src folder that leads to compilation error. This should be addressed in build script. Maybe 1.7.13 can address this.

[litespeedtech]

build.sh should have taken care of it with
preparelibquic()
it check out lsquic git repo, then did git submodule update --init --recursive, should checkout a copy of lshpack.
I not sure what causes the problem in your environment.

[istiak101]

On early versions of preparelibquic() it was copied to src folder

Also another thing is libstdc++.a file have another name on RHEL 8 packages libstdc++fs.a
https://centos.pkgs.org/8-stream/centos-appstream-aarch64/libstdc++-devel-8.4.1-1.el8.aarch64.rpm.html

openlitespeed/build.sh

Line 575 in 568a8b6

STDC_LIB=`g++ -print-file-name='libstdc++.a'`

[litespeedtech]

You can try the latest v1_7 branch,
Added a fixed symbolic link for src/lshpack,
Updated build.sh, try libstdc++fs.a if libstdc++.a is not available.

Do you have any plan on building ARM aarch64 lsphp binaries for webadmin and other usage? As currently you don't provide any ARM binaries, adding litespeed.repo in aarch64 breaks yum/dnf.
https://github.com/litespeedtech/openlitespeed/blob/v1_7/dist/install.sh

[litespeedtech]

No plan to build the ARM repo.
we can host the ARM lsphp binary for webadmin if some provide it.

[istiak101]

No problem. I would try to build lsphp binaries. If my resource allows I will surely provide lsphp binary on each release once I get used to it.

[istiak101]

This returns a new error.

Please try the latest v1_7 branch.

Now having issues with PSOL library. As ARM is pretty much newer than x86/AMD64 older versions of libraries don't have support for ARM architecture. Newer libraries support those.

https://github.com/chromium/chromium/blob/master/build/build_config.h

I am pretty much lost as I don't have any dedicated machines to build those and such long compilation time is making this hard. Any suggestions is highly appreciated.

[litespeedtech]

PSOL support wont be available for ARM as the pre-built binary is not available. It is very hard to compile it from source.
Made some adjustment to the build script. you can try the latest v1_7 branch.
If you keep the third-party/ created during previous run of build.sh, it will skip build those libraries again, can save some time.

[istiak101]

Got an executable binary at last.

[root@localhost bin]# file openlitespeed
openlitespeed: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=6e584b23f7f7eb18c40da551126f3163ebaefb10, with debug_info, not stripped, too many notes (256)

Still need to compile lsphp binary to check if everything is working correctly. Thank you very much for you time and patience.
Would you please take a look at this issue? litespeedtech/third-party#3

litespeedtech/third-party@1769072
should take care of the libcurl problem with mod_security.
Just pull third-party project, then run scripts/build_curl.sh
