Linking error occurs only in PKGBUILD fakeroot

Zaedus · 2021-07-14 03:08:57

I have a PKGBUILD which just runs make, but I ran into an issue where a library I depended on was in the AUR, so I created a git submodule, built the .so, and then added the proper c flags and linker flags which worked perfectly until I tried to build it with my PKGBUILD. I first tried to init the submodules with `git submodule update --init --recursive` in the PKGBUILD, and then settled on building it in the Makefile both worked in cloning the submodule, but failed on compilation. I've built it successfully outside of the fakeroot in many different shells. Here is the expected output, the PKGBUILD output, and my PKGBUILD.

Expected output:

$ make
git submodule update --init --recursive

Not sure what is going on since this is my first time really running into a problem with makepkg, but if there is a better way of installing an AUR package as a dependency, or if you know what is going on please do share!
Thanks in advance!

The package should probably be called riceman-git , you also can remove all empty fields like backup=() .

Using git submodules in PKGBUILDs requires a custom setup, see https://wiki.archlinux.org/title/VCS_pa … submodules .

Why did you not add it depends? The link fails as the library is not installed yet, so you would need to pass the location to the linker.

Since the package I depend on, libcurlpp, is only available in the AUR, I need to build and install it manually along with my package.

This is common - and the proper course of action is not to do any such git submodule or try to build the dependency as part of your PKGBUILD. You just list it as a dependency. That's it.

Then when you want to install your package, you build and install the dependency (libcurlpp) first.

Well I think for the sake of consistency, I shouldn't expect that the end user know to install libcurlpp prior to installing my program. I mean there has to be a way to install it as a dependency despite it being from the AUR.

Okay, this helped a lot. I looked at the wiki link you sent and instead built the submodules in the prepare() function instead, and now it builds successfully! Thank you!

You should expect it if you list it in the depends array - that's what that's for!

There is. `makepkg -si --asdeps`.

Thank you for all of your help Trilby! So here's the route that I decided to go. Instead of compiling curlpp into a dynamic library I just added it's include folder to the include path and then compiled all of the source files along with my source files. This way I don't need to worry about installing the dynamic library and all the potential problems that could arise from that (ex: someone tries to install the curlpp AUR package). Again, thank you!
