Can confirm build fails in chroot without options=(!lto)

Hi @VorpalWay! I have never had any issues with the lto option, and it seems like you were the only one who ever posted about that. Do you do anything differently?

Hi! options=(!lto) still seems to be needed, and hasn't been added. I pointed this out almost a year ago in the comments below. I assume you missed it?

PKGBUILD version from PabloTomsEscobar worked perfectly fine but unlike version 13.1, the new version required texinfo installed:

https://archlinux.org/packages/core/x86_64/texinfo/

Should it be added as dependency?

I edited the PKGBUILD with the newer version:

Hi,

The build fails for me. As the build log is quite long, I have posted it to a pastebin. The relevant lines seem to be:

../../opcodes/../../opcodes/ft32-dis.c:30:30: error: type of ‘ft32_opc_info’ does not match original declaration [-Werror=lto-type-mismatch]

and

Note: I'm building in a clean chroot using aurutils (analogous to using extra-x86_64-build from devtools). However, building outside a chroot with plain makepkg does not solve the issue.

Hello @aviel . There are currently several issues with building the package:

• current PKGBUILD implies guile library version 2.2, while it was updated to 3.0 recently; just removing that condition seems working nice (also, regular gdb is built in arch without guile version restriction);

• there is a compiler error related to the readline library update leading to violating const-correctness rules, it is fixed in regular gdb build with the following patch https://github.com/archlinux/svntogit-packages/blob/packages/gdb/trunk/readline8.patch

I've fixed the issues. See the patch and the fixes description here: https://paste.debian.net/1260718/. Please consider applying the changes.

Unfortunately the build fails if lto is enabled. The output is a bit mangled due to make -j32 and the parallel subprocesses outputting on top of each other.

Adding !lto to options solves this. However I suspect this is not the correct solution as the standard gdb is not built with !lto.
