Hi!<br>
<br>
In order to narrow down the problem you can do two things:<br>
<br>
1. Run the g++ preprocessor (with -E) and store its output. Then check
whether ag++ can compile the preprocessed code.<br>
<br>
I would expect this to be problem of the ac++ preprocessor. Therefore,
it is possible that this works. If it does not and g++ is able to
compile the preprocessed code, send it to me and I'll do the rest. If
it does, continue with 2.<br>
<br>
2. Download

unpack, and execute the following commands:<br>
<br>
ag++ --c_compiler i386-elf-g++ --gen_config<br>
<br>
=> generates a parser configuration file 'puma.config'<br>
<br>
./parser --dump-cpp --config puma.config --lang-c++ <include paths
etc> main.cpp<br>
<br>
=> This should run the ac++ preprocessor.<br>
<br>
You can compare the result with the output of the g++ preprocessor.<br>
<br>
Let me know what the result is. Better use a direct mail. There is no
need to bother other people on this list with too many details.<br>
<br>
Cheers,<br>

I have a header file "stdio.h" that has many lines in the format<br>
<br>
__externC argument fn(params) __THROW;<br>
<br>
__externC expands to extern "C" (as expected) and __THROW to throw()
but on some lines i get the message:<br>
<br>

This is weird since for some lines there are no problem and on other it
complains...<br>

<br>
as one can see he does only complain for some of the lines (until line
155 he is happy about all those __externC), not all...<br>
<br>
Is there a way i can further narrow down this problem?<br>
<br>
