I'm not sure whether it's really necessary to check for zlib -- does
Emacs even build without png support these days? -- but perhaps it is.
Anyway, I wrote the obvious:
AC_CHECK_LIB(z, inflateInit2, HAVE_ZLIB=yes, HAVE_ZLIB=no)
And that fails with:
/home/larsi/src/emacs/trunk/conftest.c:118: undefined reference to
`inflateInit2'
But inflateInit2 definitely exists (it's the function decompress.c
uses).
However, running strings over libz says:
inflateReset
inflateReset2
inflateInit2_
inflateInit_
And
AC_CHECK_LIB(z, inflateInit2_, HAVE_ZLIB=yes, HAVE_ZLIB=no)
works!
What's up with that?
