Hi Neal! (In reply to comment #0) > /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/x86_64-redhat-linux/bits/gthr-default.h:251:1: > error: pasting "__gthrw_" and "/* Android's C library does not provide > pthread_cancel, check for > `pthread_create' instead. */" does not give a valid preprocessing token > I had similar problem compiling marss using scons. The quick fix was to move the comment '/* Android .... */' in 'gthr-default.h:244' outside of '__gthrw_(..)' arguments like this: static inline int __gthread_active_p (void) { /* Android's C library does not provide pthread_cancel, check for `pthread_create' instead. */ static void *const __gthread_active_ptr = __extension__ (void *) &__gthrw_( #ifndef __BIONIC__ pthread_cancel #else pthread_create #endif ); return __gthread_active_ptr != 0; } This fixed the problem. If you need, I can make a patch. Thanks. I know how to fix it myself - I want it fixed upstream. gcc-4.6.1-8.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/gcc-4.6.1-8.fc16 Package gcc-4.6.1-8.fc16: * should fix your issue, * was pushed to the Fedora 16 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing gcc-4.6.1-8.fc16' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/gcc-4.6.1-8.fc16 then log in and leave karma (feedback). gcc-4.6.1-8.fc16 has been pushed to the Fedora 16 stable repository. If problems still persist, please make note of it in this bug report. |
Description of problem: -C flag cannot be used with gcc because of header file gthr-default.h It contains: static inline int __gthread_active_p (void) { static void *const __gthread_active_ptr = __extension__ (void *) &__gthrw_( /* Android's C library does not provide pthread_cancel, check for `pthread_create' instead. */ But __gthrw_ is a macro, so with -C flag, token pasting fails ---- hello.cc #include <iostream> ----- /usr/bin/gcc -C -o stuff hello.cc In file included from /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/x86_64-redhat-linux/bits/gthr.h:162:0, from /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/ext/atomicity.h:34, from /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/bits/ios_base.h:41, from /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/ios:43, from /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/ostream:40, from /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/iostream:40, from hello.cc:1: /usr/lib/gcc/x86_64-redhat-linux/4.6.0/../../../../include/c++/4.6.0/x86_64-redhat-linux/bits/gthr-default.h:251:1: error: pasting "__gthrw_" and "/* Android's C library does not provide pthread_cancel, check for `pthread_create' instead. */" does not give a valid preprocessing token Version-Release number of selected component (if applicable): libstdc++-devel-4.6.0-9.fc15.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3.
