gcc compiler
gcc -c -I//modeltech/include app.c
ld -G -Bsymbolic -o app.so app.o -lc
cc compiler
64-bit Solaris platform
cc -c -I//modeltech/include app.c
ld -G -Bsymbolic -o app.so app.o -lc
Compiling and linking C applications for PLI/VPI/DPI UM-571
When using -Bsymbolic with ld, all symbols are first resolved within the shared library at
link time. This will result in a list of undefined symbols. This is only a warning for shared
libraries and can be ignored.
gcc compiler
gcc -c -I/modeltech/include -m64 -fPIC app.c
gcc -shared -o app.so -m64 app.o
This was tested with gcc 3.2.2. You may need to add the location of libgcc_s.so.1 to the
LD_LIBRARY_PATH environment variable.
cc compiler
32-bit HP700 platform
cc -v -xarch=v9 -O -I/modeltech/include -c app.c
ld -G -Bsymbolic app.o -o app.so
When using -Bsymbolic with ld, all symbols are first resolved within the shared library at
link time. This will result in a list of undefined symbols. This is only a warning for shared
libraries and can be ignored.
A shared library is created by creating object files that contain position-independent code
(use the +z or -fPIC compiler argument) and by linking as a shared library (use the -b linker
argument).
If your PLI/VPI/DPI application uses anything from a system library, you’ll need to specify
that library when you link your PLI/VPI/DPI application. For example, to use the standard
C library, specify ‘-lc’ to the ‘ld’ command.
gcc compiler
gcc -c -fPIC -I//modeltech/include app.c
ld -b -o app.sl app.o -lc
cc compiler
cc -c +z +DD32 -I//modeltech/include app.c
ld -b -o app.sl app.o -lc
Note that -fPIC may not work with all versions of gcc.
