[debian-mysql] Bug#424276: libmysqlclient15-dev: depends on removed kernel header asm/atomic.h

[Steve Langasek]

Package: libmysqlclient15-dev
Version: 5.0.38-1
Severity: serious
Tags: sid lenny

Hi guys,

Packages build-depending on libmysqlclient15-dev will fail to build in
unstable on (at least) amd64 systems using the new linux-libc-dev package in
place of the obsoleted linux-kernel-headers, because my_global.h has a
dependency on asm/atomic.h:

 gcc -DHAVE_CONFIG_H -I. -I. -I. -D_REENTRANT -D_GNU_SOURCE -I/usr/include -O3 -DDBUG_OFF -I/usr/include/mysql -DBIG_JOINS=1 -g -Wall -O2 -MT libmyodbc3_la-catalog.lo -MD -MP -MF .deps/libmyodbc3_la-catalog.Tpo -c catalog.c  -fPIC -DPIC -o .libs/libmyodbc3_la-catalog.o
In file included from ../MYODBC_MYSQL.h:11,
                 from myodbc3.h:37,
                 from catalog.c:44:
/usr/include/mysql/my_global.h:353:24: error: asm/atomic.h: No such file or directory
make[3]: *** [libmyodbc3_la-catalog.lo] Error 1

According to kernel upstream[1], asm/atomic.h is not an appropriate header
for inclusion from userspace; and indeed, on some architectures such as
i386, libmysqlclient works fine without HAVE_ATOMIC_ADD being defined.

I suspect that a simple rebuild (i.e., binNMU) of mysql-dfsg-5.0 against
linux-libc-dev would be enough to fix the symptoms of this bug, but I'm
filing a sourceful bug report instead for two reasons:

- not all buildds have linux-libc-dev installed yet, and this won't be
  enforced for some time, making it difficult to get this issue covered for
  all archs in a timely manner through binNMUs
- even if asm/atomic.h is present on the system, it is still an error for
  libmysqlclient15-dev to depend on it, and this is a bug in the source
  package which should be fixed by hard-disabling the check.

Please fix this bug ASAP so that developing against libmysqlclient on
amd64/unstable works again.

Thanks,
