Trouble with PHP4.0

Hi there, i am currently trying to install Apache 1.3.14 with PHP 4.0.2 , but i'm getting a weird pb when i'm compiling apache, the configure that i have done for php is : ./configure --with-mysql --with-gd=../gd-1.8.3 --enable-ftp --enable-track-vars --with-apache=../apache_1.3.14 then i've done : make, make install Apache part : the configure : ./configure --prefix=/opt/www --activate-module=src/modules/php4/libphp4.a everything is ok but when i do : make , i have these errors : hp4 -lpam -lpng -lz -lgd -lm -lcrypt -lcrypt modules/php4/libphp4.a(file.o): In function `php_if_tempnam': /root/INSTALL/php-4.0.2/ext/standard/file.c(.text+0xe5d): warning: tempnam() possibly used unsafely; consider using mkstemp() /root/INSTALL/gd-1.8.3/libgd.a(gd_png.o): In function `gdPngErrorHandler': gd_png.o(.text+0x34): undefined reference to `png_get_error_ptr' /root/INSTALL/gd-1.8.3/libgd.a(gd_png.o): In function `gdPngReadData': gd_png.o(.text+0x90): undefined reference to `png_get_io_ptr' /root/INSTALL/gd-1.8.3/libgd.a(gd_png.o): In function `gdPngWriteData': gd_png.o(.text+0xbc): undefined reference to `png_get_io_ptr' /root/INSTALL/gd-1.8.3/libgd.a(gd_png.o): In function `gdImageCreateFromPngCtx': gd_png.o(.text+0x149): undefined reference to `png_check_sig' gd_png.o(.text+0x16e): undefined reference to `png_create_read_struct' gd_png.o(.text+0x19f): undefined reference to `png_create_info_struct' gd_png.o(.text+0x1f9): undefined reference to `png_set_sig_bytes' gd_png.o(.text+0x20d): undefined reference to `png_set_read_fn' gd_png.o(.text+0x21e): undefined reference to `png_read_info' gd_png.o(.text+0x244): undefined reference to `png_get_IHDR' gd_png.o(.text+0x258): undefined reference to `png_set_strip_16' gd_png.o(.text+0x26d): undefined reference to `png_set_packing' gd_png.o(.text+0x293): undefined reference to `png_set_strip_alpha' gd_png.o(.text+0x2bf): undefined reference to `png_get_PLTE' gd_png.o(.text+0x2cf): undefined reference to `png_get_valid' gd_png.o(.text+0x303): undefined reference to `png_get_tRNS' gd_png.o(.text+0x417): undefined reference to `png_get_valid' gd_png.o(.text+0x438): undefined reference to `png_get_tRNS' gd_png.o(.text+0x4a2): undefined reference to `png_get_valid' gd_png.o(.text+0x4bf): undefined reference to `png_get_tRNS' gd_png.o(.text+0x5a4): undefined reference to `png_set_dither' gd_png.o(.text+0x5b5): undefined reference to `png_read_update_info' gd_png.o(.text+0x5c3): undefined reference to `png_get_rowbytes' gd_png.o(.text+0x603): undefined reference to `png_destroy_read_struct' gd_png.o(.text+0x649): undefined reference to `png_destroy_read_struct' gd_png.o(.text+0x683): undefined reference to `png_read_image' gd_png.o(.text+0x690): undefined reference to `png_read_end' gd_png.o(.text+0x6ce): undefined reference to `png_destroy_read_struct' gd_png.o(.text+0x7b1): undefined reference to `png_destroy_read_struct' /root/INSTALL/gd-1.8.3/libgd.a(gd_png.o): In function `gdImagePngCtx': gd_png.o(.text+0x915): undefined reference to `png_create_write_struct' gd_png.o(.text+0x94a): undefined reference to `png_create_info_struct' gd_png.o(.text+0x9ac): undefined reference to `png_destroy_write_struct' gd_png.o(.text+0x9cd): undefined reference to `png_set_write_fn' gd_png.o(.text+0xad9): undefined reference to `png_set_IHDR' gd_png.o(.text+0xb56): undefined reference to `png_set_tRNS' gd_png.o(.text+0xcd7): undefined reference to `png_set_PLTE' gd_png.o(.text+0xceb): undefined reference to `png_write_info' gd_png.o(.text+0xcfc): undefined reference to `png_set_packing' gd_png.o(.text+0xdf4): undefined reference to `png_write_image' gd_png.o(.text+0xe08): undefined reference to `png_write_end' gd_png.o(.text+0xe53): undefined reference to `png_write_image' gd_png.o(.text+0xe67): undefined reference to `png_write_end' gd_png.o(.text+0xe80): undefined reference to `png_destroy_write_struct' *** Error code 1 Stop in /root/INSTALL/apache_1.3.14/src. *** Error code 1 Stop in /root/INSTALL/apache_1.3.14. *** Error code 1 -------- Anyone can help ?
