Dear All I am trying to create a rpm for Yacas version 1.0.63 with the command: rpmbuild -ba /usr/src/redhat/SPECS/yacas.spec but I am getting the errors below. Any ideas? I may be needing to install the development tools. Is there some way of doing that with 'yum groupinstall'? Thanks in advance, Paul -------------------------------- make[1]: Leaving directory `/usr/src/redhat/BUILD/yacas-1.0.63' + /usr/lib/rpm/find-debuginfo.sh /usr/src/redhat/BUILD/yacas-1.0.63 0 blocks find: /tmp/yacas-1.0.63-root/usr/lib/debug: No such file or directory + /usr/lib/rpm/redhat/brp-compress + /usr/lib/rpm/redhat/brp-strip-static-archive /usr/bin/strip + /usr/lib/rpm/redhat/brp-strip-comment-note /usr/bin/strip /usr/bin/objdump + /usr/lib/rpm/brp-python-bytecompile + /usr/lib/rpm/redhat/brp-java-repack-jars Processing files: yacas-1.0.63-1 Executing(%doc): /bin/sh -e /var/tmp/rpm-tmp.89573 + umask 022 + cd /usr/src/redhat/BUILD + cd yacas-1.0.63 + DOCDIR=/tmp/yacas-1.0.63-root/usr/share/doc/yacas-1.0.63 + export DOCDIR + rm -rf /tmp/yacas-1.0.63-root/usr/share/doc/yacas-1.0.63 + /bin/mkdir -p /tmp/yacas-1.0.63-root/usr/share/doc/yacas-1.0.63 + cp -pr docs/changes.html docs/infobalk.html docs/infoindex.html docs/informatie.html docs/licence.html docs/links.html docs/manicon.html docs/manindex.html docs/mybench2.html docs/navbalk.html docs/navinform.html docs/navman.html docs/todo.html docs/yacas.html docs/balk.gif docs/cha1.gif docs/cha2.gif docs/cred1.gif docs/cred2.gif docs/info1.gif docs/info2.gif docs/lice1.gif docs/lice2.gif docs/mail1.gif docs/mail2.gif docs/rel1.gif docs/rel2.gif docs/stat1.gif docs/stat2.gif docs/yacas.gif docs/yacaslogo.gif /tmp/yacas-1.0.63-root/usr/share/doc/yacas-1.0.63 + exit 0 Requires(rpmlib): rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 Requires: libc.so.6 libc.so.6(GLIBC_2.0) libc.so.6(GLIBC_2.1) libc.so.6(GLIBC_2.3) libc.so.6(GLIBC_2.4) libdl.so.2 libdl.so.2(GLIBC_2.0) libdl.so.2(GLIBC_2.1) libgcc_s.so.1 libgcc_s.so.1(GCC_3.0) libm.so.6 libstdc++.so.6 libstdc++.so.6(CXXABI_1.3) libyacas.so.0 libyacasnumbers.so.0 libyacasplatform.so.0 rtld(GNU_HASH) Processing files: yacas-debuginfo-1.0.63-1 Checking for unpackaged file(s): /usr/lib/rpm/check-files /tmp/yacas-1.0.63-root error: Installed (but unpackaged) file(s) found: /usr/bin/yacas_client /usr/bin/ytxt2tex /usr/lib/libcyacas.a /usr/lib/libcyacas.la /usr/lib/libcyacas.so /usr/lib/libcyacas.so.0 /usr/lib/libcyacas.so.0.0.0 /usr/lib/libyacas.a /usr/lib/libyacas.la /usr/lib/libyacas.so /usr/lib/libyacas.so.0 /usr/lib/libyacas.so.0.0.0 /usr/lib/libyacasnumbers.a /usr/lib/libyacasnumbers.la /usr/lib/libyacasnumbers.so /usr/lib/libyacasnumbers.so.0 /usr/lib/libyacasnumbers.so.0.0.0 /usr/lib/libyacasplatform.a /usr/lib/libyacasplatform.la /usr/lib/libyacasplatform.so /usr/lib/libyacasplatform.so.0 /usr/lib/libyacasplatform.so.0.0.0 /usr/lib/yacas/example.a /usr/lib/yacas/example.la /usr/lib/yacas/example.so /usr/lib/yacas/filescanner.a /usr/lib/yacas/filescanner.la /usr/lib/yacas/filescanner.so /usr/lib/yacas/forth.a /usr/lib/yacas/forth.la /usr/lib/yacas/forth.so /usr/lib/yacas/libmath.a /usr/lib/yacas/libmath.la /usr/lib/yacas/libmath.so /usr/lib/yacas/libmath.so.0 /usr/lib/yacas/libmath.so.0.0.0 /usr/lib/yacas/opengl.a /usr/lib/yacas/opengl.la /usr/lib/yacas/opengl.so /usr/lib/yacas/pcre.a /usr/lib/yacas/pcre.la /usr/lib/yacas/pcre.so /usr/lib/yacas/yacas_gsl.a /usr/lib/yacas/yacas_gsl.la /usr/lib/yacas/yacas_gsl.so RPM build errors: Installed (but unpackaged) file(s) found: /usr/bin/yacas_client /usr/bin/ytxt2tex /usr/lib/libcyacas.a /usr/lib/libcyacas.la /usr/lib/libcyacas.so /usr/lib/libcyacas.so.0 /usr/lib/libcyacas.so.0.0.0 /usr/lib/libyacas.a /usr/lib/libyacas.la /usr/lib/libyacas.so /usr/lib/libyacas.so.0 /usr/lib/libyacas.so.0.0.0 /usr/lib/libyacasnumbers.a /usr/lib/libyacasnumbers.la /usr/lib/libyacasnumbers.so /usr/lib/libyacasnumbers.so.0 /usr/lib/libyacasnumbers.so.0.0.0 /usr/lib/libyacasplatform.a /usr/lib/libyacasplatform.la /usr/lib/libyacasplatform.so /usr/lib/libyacasplatform.so.0 /usr/lib/libyacasplatform.so.0.0.0 /usr/lib/yacas/example.a /usr/lib/yacas/example.la /usr/lib/yacas/example.so /usr/lib/yacas/filescanner.a /usr/lib/yacas/filescanner.la /usr/lib/yacas/filescanner.so /usr/lib/yacas/forth.a /usr/lib/yacas/forth.la /usr/lib/yacas/forth.so /usr/lib/yacas/libmath.a /usr/lib/yacas/libmath.la /usr/lib/yacas/libmath.so /usr/lib/yacas/libmath.so.0 /usr/lib/yacas/libmath.so.0.0.0 /usr/lib/yacas/opengl.a /usr/lib/yacas/opengl.la /usr/lib/yacas/opengl.so /usr/lib/yacas/pcre.a /usr/lib/yacas/pcre.la /usr/lib/yacas/pcre.so /usr/lib/yacas/yacas_gsl.a /usr/lib/yacas/yacas_gsl.la /usr/lib/yacas/yacas_gsl.so
