Build failure on x86_64 linux: relocation R_X86_64_32 can not be used
Closed this issue · 11 comments
- Linux 4.10.11
- GPRBUILD Pro 18.0w (19940713) (x86_64-pc-linux-gnu)
- gcc (GCC) 7.1.1 20170508
- gtk+ 3.22.15
I cloned the repo, ran ./configure --prefix=/usr --with-GL=no (as suggested in #9) and followed it with make PROCESSORS="$(nproc)"
This resulted in a relocation error:

Applying this patch appears to correct the issue:

Is there anything blocking a fix?
nothing, sorry for the delay! Just that we can't seem to reproduce out-of-the-box (tried on a relatively recent Ubuntu and a recently recent RedHat). What's your platform, just for the record?
Most of the details were listed in the bug report. Currently I'm using Arch Linux as a base which is essentially vanilla. If you want to see the build flags for gcc I can provide those.
One unique thing Arch does perhaps is that we remove most static libraries which aren't necessary which means gtkada is linking against shared objects which must be fPIC on x86 as I understand it.
@Earnestly, could you please try the following patch instead, which uses the PIC_Option attribute? (Sorry, I couldn't make the time to install Arch Linux and do the test myself).

Great, I can confirm your patch does work.
Don't worry about installing Arch Linux; so long as you use relatively up to date software which has minimal tampering from upstream defaults, it should be fine. Shared libraries on x86_64 absolutely need PIC, gcc will even force it. http://unix.derkeiler.com/Newsgroups/comp.unix.programmer/2007-07/msg00513.html
Thank you!
Reopened on second consideration, I jumped the gun a bit since while the patch works, it's still only a patch
and done :)
I have this problem, but neither of the patches work. I am on:
- Debian 9 Jessie. (linux 4.9.210-1)
- GPRBUILD Community 2018 (20180524) (x86_64-pc-linux-gnu)
- gcc (GCC) 7.3.1 20180525 (for GNAT Community 2018 20180524)
- gtk+ 3.8.3
After a kernel update to 5.8.0 it seems the issue is back:
If I run:
./configure ./configure --with-GL=no
make
I get stuck with the error aforementioned.

The system is:
- OpenSuse Tumbleweed
- GPRBUID Community 2019 (64bit)
- GCC 10.2.1 20200805 x86_64-suse-linux
- gtk+ 3.24.22
How to proceed ?
Thanks.

I have an error with gtkada-2021-x86_64-linux-bin : relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
Enter the name of the directory in which you would like to install GtkAda
[/opt/gtkada]
Are you now ready to proceed with the installation [Y/n] ?
