ModelSim SE User’s Manual
ld -shared -E -Bsymbolic -o app.so app.o -lc
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. If you are using ModelSim RedHat version 6.0 through 7.1,
you also need to add the -noinhibit-exec switch when you specify -Bsymbolic.
The compiler switch -freg-struct-return must be used when compiling any FLI application
code that contains foreign functions that return real or time values.
64-bit Linux is supported on RedHat Linux Advanced Workstation 2.1 for Itanium 2.
gcc compiler (gcc 3.2 or later)
gcc -c -fPIC -I//modeltech/include app.c
ld -shared -Bsymbolic -E --allow-shlib-undefined -o app.so app.o
If your PLI/VPI/DPI application requires a user or vendor-supplied C library, or an
additional system library, you will need to specify that library when you link your PLI/VPI/
DPI application. For example, to use the system math library libm, specify -lm to the ld
command:
gcc -c -fPIC -I//modeltech/include math_app.c
ld -shared -Bsymbolic -E --allow-shlib-undefined -o math_app.so math_app.o -lm
64-bit Linux for Opteron and Athlon 64 platforms
32-bit Solaris platform
64-bit Linux is supported on RedHat Linux EWS 3.0 for Opteron and Athlon 64.
gcc compiler (gcc 3.2 or later)
gcc -m64 -c -fPIC -I//modeltech/include app.c
ld -m elf_x86_64 -shared -Bsymbolic -E --allow-shlib-undefined -o app.so \
app.o
The -m64 and -m elf_x86_64 switches are required to compile for 64-bit operation. To
compile for 32-bit operation, use the -m32 argument instead of -m64 at the gcc command
line. These arguments for 32-bit or 64-bit operation are required only if the desired
operation differs from the default gcc settings.
If your PLI/VPI/DPI application requires a user or vendor-supplied C library, or an
additional system library, you will need to specify that library when you link your PLI/VPI/
DPI application. For example, to use the system math library libm, specify -lm to the ld
command:
gcc -m64 -c -fPIC -I//modeltech/include math_app.c
ld -m elf_x86_64 -shared -Bsymbolic -E --allow-shlib-undefined \
-o math_app.so math_app.o -lm
If your PLI/VPI/DPI application uses anything from a system library, you will 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.
