Maybe this can be fixed by disabling PCH generation when -x is passed.

Like you said, using the prefix BaseClassTemplate:: and not compiling the .h 
template file, just compiling the .c files that use this .h template file 
works fine.

 Confirmed, but the question is why do you need to generate the PCH twice? 
 Header files never produce object files, unlike in Ada.  Also removing the 
PCH
 file is enough to solve the problem.


  Perhahs, I have a concept problem. If you have a c++ template in a .h 
file without a .c file and you compile it you should obtain a .o object. I 
do not need any “.gch” file

So this happens with the 3.2.3 version.

sun1:~/test g++ -v
Reading specs from /usr/local/gcc-3.2.3/bin/../lib/gcc-lib/sparc-sun-
solaris2.9/3.2.3/specs
Configured with: ./configure --prefix=/usr/users/afernand/comp/gcc-3.2.3 -
enable-language=c,c++
Thread model: posix
gcc version 3.2.3

sun1:~/test ls -la test*
-rw-r-   1 cmarco   indra141 Mar  3 16:49 test.h
sun1:~/test g++ -m64 -x c++ -c test.h
sun1:~/test ls -la test*
-rw-r-   1 cmarco   indra141 Mar  3 16:49 test.h
-rw-r-   1 cmarco   indra672 Mar 17 09:18 test.o

Now if I use the 3.4.4 version: 

sun1:~/test g++ -v
Reading specs from /usr/local/gcc-34/bin/../lib/gcc/sparc-sun-
solaris2.9/3.4.4/specs

-enable-language=c --without-headers --disable-shared :

language=c,c++
Thread model: posix
gcc version 3.4.4 20041222 (prerelease)
 
sun1:~/test ls -la test*
-rw-r-   1 cmarco   indra141 Mar  3 16:49 test.h 
sun1:~/test  g++ -m64 -x c++ -c test.h
sun1:~/test ls -la test*
-rw-r-   1 cmarco   indra141 Mar  3 16:49 test.h
-rw-r-   1 cmarco   indra1034879 Mar 17 09:23 test.h.gch

Something have change. ¿Should I have use other options?

 file without a .c file and you compile it you should obtain a .o object.

No, you're forcing the compilation with -x c++.  Try without -x and see what the
3.2.3 compiler says.

The bottom line is that you should never compile a header file, except if you
want to get the corresponding PCH file.
