Bug 31595

My build (in a quite minimal chroot) broke with:

  CC     encparse.lo
encparse.c:39:18: error: zlib.h: No such file or directory
encparse.c:40: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘FontFilePtr’
encparse.c:84: error: expected ‘)’ before ‘f’
encparse.c:98: error: expected ‘)’ before ‘f’
encparse.c:131: error: expected ‘)’ before ‘f’
encparse.c:153: error: expected ‘)’ before ‘f’
encparse.c:198: error: expected ‘)’ before ‘f’
encparse.c:464: error: expected ‘)’ before ‘f’
[…]


I'm not sure configure.ac contains the needed bits:

# zlib
AC_CHECK_LIB(z, gzclose)


Relevant bits of config.log:

configure:11773: checking for gzclose in -lz
