I am working on an updated rpm of your library for PCLinuxOS. I was hoping for some assistance, as I am running out of ideas. I appreciated any attention you may offer to this problem. Thanks for this library. First of all, I can build the library successfully using ./configure, make, and make install. However, when I try to build it with a spec file, it comes up with all kinds of errors. I started with the spec PCLinuxOS spec file for 1.1.13, then looked for clues from Mandriva, Fedora and the included cln.spec.in. Here seems to be the environment created for building the rpm: + CFLAGS='-O2 -pipe -Wp,-D_FORTIFY_SOURCE=2 -fomit-frame-pointer -march=i586 -mtune=generic -fasynchronous-unwind-tables' + export CFLAGS + CXXFLAGS='-O2 -pipe -Wp,-D_FORTIFY_SOURCE=2 -fomit-frame-pointer -march=i586 -mtune=generic -fasynchronous-unwind-tables' + export CXXFLAGS + FFLAGS='-O2 -pipe -Wp,-D_FORTIFY_SOURCE=2 -fomit-frame-pointer -march=i586 -mtune=generic -fasynchronous-unwind-tables' Here are the errors when I build without any other modifications: checking whether build environment is sane... /usr/share/automake-1.11/am/depend2.am: am__fastdepCCAS does not appear in AM_CONDITIONAL /usr/share/automake-1.11/am/depend2.am: The usual way to define `am__fastdepCCAS' is to add `AM_PROG_AS' /usr/share/automake-1.11/am/depend2.am: to `configure.ac' and run `aclocal' and `autoconf' again. src/Makefile.am: Preprocessed Assembler source seen but `CCAS' is undefined src/Makefile.am: The usual way to define `CCAS' is to add `AM_PROG_AS' src/Makefile.am: to `configure.ac' and run `aclocal' and `autoconf' again. src/Makefile.am: Preprocessed Assembler source seen but `CCASFLAGS' is undefined src/Makefile.am: The usual way to define `CCASFLAGS' is to add `AM_PROG_AS' src/Makefile.am: to `configure.ac' and run `aclocal' and `autoconf' again. yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking for style of include used by make...

This leads to other errors which I'll gladly outline if necessary. Thank you for taking the time to read this, and any feedback would be appreciated. Galen
