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

And the worst thing that > I see no way to tell it to use these libraries (short of hand-patching > configure file, which seems to be not exactly the right thing to do). This is not the case. The checks from gd/config.m4 are: 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="$LIBS -lz",,) AC_CHECK_LIB(png,png_info_init, LIBS="$LIBS -lpng",,) AC_CHECK_LIB(gd, gdImageColorResolve, [AC_DEFINE(HAVE_GDIMAGECOLORRESOLVE,1,[ ])]) dnl Some versions of GD support both PNG and GIF. Check for both. AC_CHECK_LIB(gd, gdImageCreateFromPng, [AC_DEFINE(HAVE_GD_PNG, 1, [ ])]) AC_CHECK_LIB(gd, gdImageCreateFromGif, [AC_DEFINE(HAVE_GD_GIF, 1, [ ])]) AC_CHECK_LIB(gd, gdImageCreateFromXbm, [AC_DEFINE(HAVE_GD_XBM, 1, [ ])]) AC_CHECK_LIB(gd, gdImageWBMP, [AC_DEFINE(HAVE_GD_WBMP, 1, [ ])]) LIBS=$old_LIBS LDFLAGS=$old_LDFLAGS if test "$ac_cv_lib_gd_gdImageCreateFromPng" = "yes"; then AC_ADD_LIBRARY(png) AC_ADD_LIBRARY(z) fi 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. -Rasmus
