I know this is not specifically a BLFS package, but I'm trying to build it as an adjunct and helper to GIMP.
The build fails with: > rwpng.c:310:40: error: 'Z_BEST_COMPRESSION' undeclared (first use in > this function) > png_set_compression_level(png_ptr, Z_BEST_COMPRESSION); > ^ > make[2]: *** [rwpng.o] Error 1 because > rwpng.c: In function 'rwpng_version_info': > rwpng.c:52:7: error: 'ZLIB_VERSION' undeclared (first use in this > function) > ZLIB_VERSION, zlib_version); > ^ > rwpng.c:52:7: note: each undeclared identifier is reported only once > for each function it appears in > rwpng.c:52:21: error: 'zlib_version' undeclared (first use in this > function) > ZLIB_VERSION, zlib_version); > ^ The "config.log" which the executable "config.status" calls in an <exec> command has: > 364 Configured with: /usr/src/gcc-4.8.1/gcc-4.8.1/configure > --prefix=/usr --libexecdir=/usr/lib --enable-shared > --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu > --enable-languages=c,c++ --disable-multilib --disable-bootstrap > --disable-install-libiberty --with-system-zlib= I used only "--prefix=/usr --libdir=/usr/lib --includedir=/usr/include" and neither libdir nor includedir got passed. I used those hoping to help the configure script to find zlib. The "config.log" has the following lines containing "zlib." > configure:5218: checking for library containing zlibVersion > /usr/src/pngnq-1.1/pngnq-1.1/conftest.c:43: undefined reference to > `zlibVersion' > | char zlibVersion (); > | return zlibVersion (); > ac_cv_search_zlibVersion=-lz Looking at line 364 above, the "/usr/src/gcc-4.8.1/gcc-4.8.1/configure" and the fact that the configure script recognized only the "--prefix=/usr" switch got my attention. Is this a situation in which autoconf or autoreconf would work? If so, I don't now how to use those without following instructions in the book and would need help. Another possibility would be for me to edit the line "ac_cv_search_zlibVersion=-lz" but I would not know what to put in place of -lz. The "/usr/src/gcc-4.8.1" sequence made me suspect that my Package Users system was getting in the way. I tried to build pngnq as me and got exactly the same results in all areas. I'd appreciate some pointers. Dan -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
