[Pkg-net-snmp-devel] Bug#864485: net-snmp-config --base-lib-cflags is broken

[Ignacy Gawedzki]

Source: net-snmp
Severity: normal

Dear Maintainer,

The --base-lib-cflags option to net-snmp-config added by Debian
developers is broken as it outputs @LIBCFLAGS@ among others.

The problem comes from the fact that when it was introduced (version
5.4.2.1~dsfg-4), the original patch modified the configure.in file as
well. In the meantime, the structure of configure.ac has changed and
when the patch was adapted, the modification to configure.ac was
dropped, resulting in a substitution left aside.

The attached patch is an attempt to restore the original behavior. It
is meant as a replacement of debian/patches/62_add_lib_cflags.patch .

Nevertheless, the way information output by net-snmp-config
--base-lib-cflags is gathered is wrong. There shouldn't IMHO be any
GCC optimization flags like -O2 in the substitution, among others. The
variable to substitute @LIBCFLAGS@ should be carefully constructed
during the configure process instead.
