Hope this is the right mailing list.
I have strange problems with gcc version 2.96 20000731 (Red Hat Linux
7.1 2.96-98)
(obtained with the command gcc -v) and
with kernel 2.4.7-10 #1 Thu Sep 6 17:27:27 EDT 2001 i686 unknown
(otained with uname -a command)
using exception handling with shared libraries.
I have done a deep search on internet but I have not found somthing
similar to my problems.
This is the situation.
I have defined my exception class as follows in the file Exception.h
and Exception.cc
class Exception{
...
... // My basic code
...
};
and I have created a first shared library libGCASUtils.so with the
following command:
(1) compiling:
g++ -DNO_DEBUG -fPIC -DLIN -DLININTEL -DCSFDB -funsigned-char -Wall
-DCSFDB -O3 -DNDEBUG -D_REENTRANT -D_THREAD_SAFE
-D"__DEBUG__"-DNO_DEBUG -fPIC -DLIN -DLININTEL -DCSFDB -funsigned-char
-Wall -DCSFDB -O3 -DNDEBUG -I. -I.. -I/src/cleditor -I/src/clstepcore
-I/src/clutils -I/src/cldai -I -I
-I/usr/local/nana/nana-bin-2.5/include
-I/usr/local/commonC++/commoncpp-bin-2-0.99.4/include/cc++2 -c Exception.cc
(2) linking:
g++ -shared -Wl,-export-dynamic --shared-libgcc -o libGCASUtils.so
Exception.o Logger.o LoggerManager.o GenericDataVector.o Link.o Node.o
GenericDataNode.o GenericDataLink.o Graph.o
-L/usr/lib/gcc-lib/i386-redhat-linux/2.96 -lgcc
-L/usr/local/commonC++/commoncpp-bin-2-0.99.4/lib -lccgnu2 -lccext2
-pthread -ldl -lz -lxml -lxml2 -L/usr/local/nana/nana-bin-2.5/lib -lnana
at this point I have the shared library: libGCASUtils.so
Then I have a .cc file with a class ImportManager and a
method importSTEPFile(...) that throws an exception
as below reported:
class ImportManager {
static void importSTEPFile(...) throw (GCAS::Exception);
}
I have created another shared library with this class with the following
steps:
(1) compilation:
g++ -DNO_DEBUG -fPIC -DLIN -DLININTEL -DCSFDB -funsigned-char -Wall
-DCSFDB -O3 -DNDEBUG -D_REENTRANT -D_THREAD_SAFE -D"__TRACE__"

(2) linking

At this time I have a new shared library libCEScore.so.
Now I have the wollowing code in the main application:
43 try{
44
45 ImportManager::importSTEPFile(argv[1], pPartMgr);
46
47 }catch(GCAS::Exception &e){
48 e.Report();
49 LoggerManager::TRACE_INFO("main","Unable to import the
STEP file.", DEBUG_1);
50 LoggerManager::TRACE_LOCAL_STDOUT("Unable to import the
STEP file.");
51 LoggerManager::TRACE_LOCAL_STDOUT("Program aborted.");
52
53 LoggerManager::TRACE_EXIT("main","int main(int argc, char
* argv [])");
54
55 delete pPartMgr;
56 delete pLM;
57
58 cout << "Here we are" << endl;
59
60 }
61
62 cout << "Before exit" << endl;
63
64 return 0;
The compilation and linking of the code are OK as reported below
compiling main.cc
g++ -D_REENTRANT -D_THREAD_SAFE -D"__TRACE__" -D"__DEBUG__" -I. -I..

At this point I run the program with a wrong file name:
./geoModule skjs
and this is the result:
The input file skjs is not a good file!
Exception: Not a good file. Check-out trace file.
LOCAL TRACING >> Unable to import the STEP file.
LOCAL TRACING >> Program aborted.
Here we are
Segmentation fault
It seems that the exception is properly thrown,
and that the same exception is properly catched but when
the execution terminates the catch bloch (catch {})
the application crashes....???
What is the problem???
Thank's in advance for any help.
Paolo Mosna.

No, it isn't.

You'll need to ask Red Hat for assistance with their "2.96". It is their
own fork of GCC.
