Category: allegrocl Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: xypron (xypron) Assigned to: Mikel Bancroft (mutandiz) Summary: Redefinition of HAVE_BOOL Initial Comment: I tried to compile swig-2.0.4 on Debian Wheezy 64bit. I received the error below. make[1]: Entering directory `/home/myuser/src/swig-2.0.4/Source' make all-am make[2]: Entering directory `/home/myuser/src/swig-2.0.4/Source' source='Modules/allegrocl.cxx' object='Modules/allegrocl.o' libtool=no \ DEPDIR=.deps depmode=none /bin/bash ../Tools/config/depcomp \ g++ -DHAVE_CONFIG_H -I../Source/Include -I../Source/CParse -I../Source/Include -I../Source/DOH -I../Source/CParse -I../Source/Preprocessor -I../Source/Swig -I../Source/Modules -c -o Modules/allegrocl.o Modules/allegrocl.cxx In file included from Modules/allegrocl.cxx:16:0: Modules/swigmod.h:22:13: error: redeclaration of C++ built-in type bool [-fpermissive] To fix the error I commented the lines in Sources/Modules/swigmod.h which redefined bool. Please, change the configure file to detect if bool is defined and to set HAVE_BOOL in config.h. Best regards Xypron ---------------------------------------------------------------------- >Comment By: William Fulton (wsfulton) Date: 2011-06-23 05:52 Message: After reconfiguring your system installing g++, you need to rerun configure. You cannot avoid that or expect any other behaviour. The fact that you discovered your system was missing g++ when compiling SWIG rather than during configure time is not ideal and somewhat surprising. This is standard (buggy) autoconf behaviour, see: http://lists.gnu.org/archive/html/bug-autoconf/2010-05/msg00001.html. Note that we have the following macros configure.in AC_PROG_CC AC_PROG_CXX so the 2nd AC_PROG macro does not check that the tool works - this is described as buggy behaviour. I don't see any value in switching those macros around as it shifts the problem to the C compiler from the C++ compiler. If someone can find a reliable autoconf macro that checks the c++ compiler works we can put it in, otherwise I propose we leave the current behaviour as it is quite clear that a c++ compiler needs to be installed, even if it is a bit late in the configure/build/install cycle. ---------------------------------------------------------------------- Comment By: xypron (xypron) Date: 2011-06-22 23:15 Message: On my first try of compiling SWIG I first ran ./configure and only during make received an error message that g++ was missing. I installed g++ with sudo apt-get install g++ and continued make. I then ran into the error concerning HAVE_BOOL. When g++ is installed before ./configure everything runs fine. It seems the real bug is that the configure script does not check for g++. ---------------------------------------------------------------------- Comment By: xypron (xypron) Date: 2011-06-22 22:45 Message: >> with HAVE_BOOL being defined, based on a test for >> bool, in Source/Include/swigconfig.h, This is just the code that is not working, because though bool is defined, HAVE_BOOL is never set. ---------------------------------------------------------------------- Comment By: Mikel Bancroft (mutandiz) Date: 2011-06-22 22:25 Message: This does not appear to be allegrocl specific, nor can I duplicate (on a non-debian machine). Also, the suggested fix appears to already be implemented in 2.0.4, with HAVE_BOOL being defined, based on a test for bool, in Source/Include/swigconfig.h, which is generated via configure.in. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=101645&aid=3324696&group_id=1645 |
