GNAT¶

Hint

You need to install LLVM (usually depends on libedit, see #29). The supported versions are 3.5 til 5.0, but debugging is only supported with LLVM 3.5.

First configure GHDL with the proper arg ./configure --with-llvm-config. If llvm-config is not in your path, you can specify it: ./configure --with-llvm-config=LLVM_INSTALL/bin/llvm-config.
Then, build with make and install with make install.

Example:

$ cd <ghdl>
$ mkdir build
$ cd build
$ ../configure --with-llvm-config --prefix=PREFIX
$ make
$ make install

Hint

If you want to have stack backtraces on errors (like assert failure or index of out bounds), you need to configure and build libbacktrace from GCC (you don’t need to configure GCC). Then add the following arg to configure: --with-backtrace-lib=/path-to-gcc-build/libbacktrace/.libs/libbacktrace.a
