Re: PHP 4.0 Bug #4569 Updated: configure fails to

>> AC_CHECK_LIB(gd, gdImageString16, [ AC_DEFINE(HAVE_LIBGD13,1,[]) ]) >> AC_CHECK_LIB(gd, gdImagePaletteCopy, [ AC_DEFINE(HAVE_LIBGD15,1,[]) ]) >> AC_CHECK_LIB(gd, gdImageColorClosestHWB, [ >> AC_DEFINE(HAVE_COLORCLOSESTHWB,1,[ ]) ]) >> AC_CHECK_LIB(z,compress, LIBS="$LIBS -lz",,) This check fails because it tries to link gd there and dies. I don't know why it needs to put -lgd into libz check, but it does: configure:13716: checking for compress in -lz configure:13735: gcc -o conftest -g -O2 conftest.c -lz -lgd -lresolv -lm -ldl -lcrypt -lnsl -lresolv 1>&5 /usr/lib/libgd.so: undefined reference to `uncompress' /usr/lib/libgd.so: undefined reference to `png_set_dither' [skip] collect2: ld returned 1 exit status configure: failed program was: #line 13724 "configure" #include "confdefs.h" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char compress(); int main() { compress() ; return 0; } >> AC_CHECK_LIB(png,png_info_init, LIBS="$LIBS -lpng",,) Ditto here. Both these test fail, so configure assumes no PNG. >> This clearly shows that it adds -lz and -lpng to LIBS before checking for >> the PNG support. So although there may indeed be a problem somewhere, >> your analysis of it is incorrect. Well, I'm very far from being autoconf guru, that's why I cry for somebody more knowledgeable to look at it. -- Stanislav Malyshev stas@zend.com +972-3-6139665 ext.106
