[SOLVED] Samba 4.22.5-r1 fails to compile ; CFLAGS problem ?

Message

Sargastic · Post by **Sargastic** » Tue Mar 10, 2026 6:45 am

Hello,

I recently met troubles compiling samba on one computer. I have the feeling my CFLAGS definition is the culprit, but I do not see how to solve that.

What leads me to thing that is this part of the build.log, specifically the

Code: Select all

Could not find a .d dependency file, are cflags/cxxflags overwritten?

From build.log :

Code: Select all

My CFLAGS (from make.conf) are as follow, made through resolve-march-native :

Code: Select all

CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"

Any idea on how to solve this problem ?

Thanks.

LDFLAGS is missing from your snippet but can we have the full build.log & emerge --info please?

Here is the build.log (link valid for 90 days) :

Thanks. I think the .d file may be made remotely. Can you try with distcc disabled please?

Spot on !
Without distcc, Samba compiles ok. Thanks a lot.

Is there a way to disable distcc for a specific ebuild (as here) ?

You should be able to with https://wiki.gentoo.org/wiki/Knowledge_ ... er_package or https://wiki.gentoo.org/wiki//etc/portage/package.env (package.env w/ an env file that has FEATURES="${FEATURES} -distcc")
