Hi,
I'm attempting to build GCC 4.3.0 - and I thought I had succeeded until
I realised that the 'all-gcc' make target (now?) doesn't build libgcc.a.
So I'm now trying to make the 'all' target, and I'm getting a configure
error in the libgcc directory. An extract of the config.log follows:
configure:4082: g++ -c -g -O2 conftest.cc >&5
conftest.cc: In function 'int main()':
conftest.cc:13: error: 'exit' was not declared in this scope
configure:4088: $? = 1
configure: failed program was:
| /* confdefs.h. */
|
| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""
| #define PACKAGE_VERSION ""
| #define PACKAGE_STRING ""
| #define PACKAGE_BUGREPORT ""
| /* end confdefs.h. */
|
| int
| main ()
| {
| exit (42);
| ;
| return 0;
| }
As you can see, the test program autoconf is generating does not include
<cstdlib>, so g++ is perfectly correct in erroring.
I'm not certain how to fix this - is it just a case of hacking the
config.in file? I'd appreciate any help.
Compiling GCC 4.3.0 from source using G++ 4.1.2, autoconf 2.61, and
automake 1.10.
Thanks,
James
