CentOS 7 - Samba Server + Utils build failing

For Developers
1

Unable to resolve this issue on CentOS 7.6.1810 (remi, epel repo). I even tried building Samba 4.10.5 from src to get the latest libs.

Just tested with latest dev version (samba4 + utils) and compiled fine for me?
Try do a clean got clone for the openwrt dev branch and rebuild.

Did a complete new git clone and build, seems to be the same issue. Here's the full log from e2fs compilation

Not really sure whats going on there, we explicitly build a working libcom_err for samba, which samba seems to pick up, yet the version number check fails.

Can you check if there is a valid:

openwrt/staging_dir/target-arm_cortex-a9+vfpv3_musl_eabi/usr/lib/pkgconfig/com_err.pc
openwrt/staging_dir/target-arm_cortex-a9+vfpv3_musl_eabi/pkginfo/libcomerr.provides
5

Here it is:

[openwrt@servme ~]$ cat openwrt/staging_dir/target-arm_cortex-a9+vfpv3_musl_eabi/usr/lib/pkgconfig/com_err.pc
prefix=/usr
exec_prefix=/usr
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: com_err
Description: Common error description library
Version: 1.44.5
Requires:
Cflags: -I${includedir}/et -I${includedir}
Libs: -L${libdir} -lcom_err
Libs.private: 
[openwrt@servme ~]$ cat openwrt/staging_dir/target-arm_cortex-a9+vfpv3_musl_eabi/pkginfo/libcomerr.provides
libc.so
libcom_err.so.0
libcom_err.so.0.0
libgcc_s.so.1
libuuid.so.1
libuuid.so.1.3.0

mhh looks good, no clue than why the check fails.
Upload your openwrt/build_dir/target-arm_cortex-a9+vfpv3_musl_eabi/samba-4.9.8/bin/config.log maybe something sticks out.

PS: I'm in the process on getting 4.10.6 ready, maybe the new version will fix your problem.

Could this be related to gnutls version in any case? Here's the config.log you've requested. https://gist.github.com/gxgani/1abdfb52aeaacdac8cb36d200cc7b320

I am able to build on debian 10 rc2 (vm) but my server's on CentOS 7.

Only if you build with SERVER_AD_DC otherwise gnutls is not needed.

Hmm..
The config log ends

From what I've researched, that's i686 library which isn't available on CentOS 7 x86_64

After installing i686 library for gcc and dependencies, I was able to go through the library com_err issue but now it's failing at:

Any clue?

not really looks like something is breaking the openwrt build system, since _FORTIFY_SOURCE is defined by the global openwrt sdk.

PS: Maybe its better to use one of the openwrt docker containers to build openwrt, to avoid those problems.

Thanks, switched Openwrt docker container to build for now.
