-fix_hardcoded_libdirs_in_extmod_linker_cmd-sagelib.patch /trac_9896
-fix_hardcoded_libdirs_in_extmod_linker_cmd-sagelib.patch]. This seems
fine, but the messages like "Library dir found in dynamic linker
command..." don't actually appear in any log (unless you pipe the whole
thing through tee, perhaps, but I haven't tried this yet). (I'm assuming
that, since I upgraded from 4.5.3 on OS X, the situation dealt with in the
loop would occur, and I searched through all of the logs without finding
this string.) I was hoping that they would appear in the sage-4.6.rc0
log, but no. Is there anything to be done about this?
{{{
#!python
if ldso_cmd[i][:2] == "-L":
libdir = os.path.normpath(ldso_cmd[i][2:])
self.debug_print(
"Library dir found in dynamic linker command: " +
"\"%s\"" % libdir)
if libdir != sage_libdir:
self.compiler.warn(
"Replacing library search directory in linker "
+
"command:\n \"%s\" -> \"%s\"\n" % (libdir,
sage_libdir))
ldso_cmd[i] = "-L"+sage_libdir
}}}
No, that's intentional. {{{self.debug_print()}}} only produces output if
{{{DISTUTILS_DEBUG}}} is set.
In contrast, {{{self.compiler.warn()}}} always prints a message, so you
should find ''"warning: Replacing library search directory ..."'' in the
logs of the installations you had moved:
{{{
#!sh
$ grep "^warning: " install.log
}}}
or
{{{
#!sh
$ grep "^warning: Replacing" spkg/logs/sage-*
}}}
should show these.
