I'm recompiling gcc-4.1.1 in order to user NVIDIA-SDK, but I'm having an
error I'm trying to solve.
Gcc-4.1.1 configure so:
"../gcc-4.1.1/configure --prefix=/usr --libexecdir=/usr/lib
--enable-shared --enable-threads=posix --enable-__cxa_atexit
--enable-clocale=gnu
--enable-languages=c,ada,c++,fortran,java,objc,obj-c++,treelang
--with-mpfr=usr --with-gmp=/usr --with-system-zlib --with-x
--enable-java-awt=gtk,xlib --enable-gtk-cairo --enable-java-gc=boehm
--with-libart-prefix=/usr --without-system-unwind
--enable-libstdcxx-allocator=mt --enable-libstdcxx-debug".
While making in java I receive this error:
"./gcj-dbtool -n classmap.db || touch classmap.db
Unexpected error from pthread_mutex_trylock
/bin/sh: line 1: 15360 Aborted ./gcj-dbtool -n classmap.db
make[3]: Leaving directory `/sources/gcc-build/i686-pc-linux-gnu/libjava'
make[2]: Leaving directory `/sources/gcc-build/i686-pc-linux-gnu/libjava'
make[1]: Leaving directory `/sources/gcc-build'"
Two things I noticed. First, I think that the the error is hrom the
boehm garbage collector. From boehm-gc/pthread_support.c:
switch(pthread_mutex_trylock(lock)) {
case 0:
# ifdef LOCK_STATS
++GC_spin_count;
# endif
return;
case EBUSY:
break;
default:
ABORT("Unexpected error from pthread_mutex_trylock");
}
So, you could try removing --enable-java-gc=boehm. However, I think
you can ignore the error. Here's from libjava/Makefile.am:
## The .db file. This rule is only used for native builds, so it is
## safe to invoke gcj-dbtool.
$(db_name): gcj-dbtool$(EXEEXT)
## In case it exists already.
@rm -f $(db_name)
## We don't actually care if it fails -- if it does, just make an
## empty file. This is simpler than trying to discover when mmap is
## not available.
./gcj-dbtool -n $(db_name) || touch $(db_name)
Does make return unsuccessfully?
