75 The linker can't find -lieee
76 ----------------------------
77
78 This can happen because your libraries don't match your version of
79 gcc. Some recent Linux distributions don't include a libieee.a file
80 because IEEE support is now the default and the library is no longer
81 needed, but the gcc specs file still adds -lieee to the linker command
82 if gcc is invoked with the -mieeefp flag. I believe that you should
83 be able to fix this by editing the gcc specs file. In it, you should
84 find something like this:
85
86 %{!shared: %{mieee-fp:-lieee} %{p:-lgmon} %{pg:-lgmon} \
87 %{!ggdb:-lc} %{ggdb:-lg}}
88
89 changing it to
90
91 %{!shared: %{p:-lgmon} %{pg:-lgmon} %{!ggdb:-lc} %{ggdb:-lg}}
92
93 should keep gcc from adding -lieee to the link command. You can find
94 the location of the specs file by running the command gcc -v.

99 A binary release of g77 that should work with gcc 2.7.2 is available
100 from sunsite.unc.edu in the directory /pub/Linux/devel/lang/fortran.
101 There is also a Debian package for g77.
