Re: [M-Labs devel] LM32 testbench files modelsim compile error
You can use gcc-core from http://ftp.gnu.org/gnu/gcc/gcc-4.5.4/ Indeed you need several packages/dependencies in order to compile gcc configure script will generally tell you what to install (like what you pasted). To compile a lm32-elf toolchain you can have a look there: http://milkymist.org/wiki/index.php?title=Compiling_a_lightweight_Mico32_toolchain Just use gcc 4.5.4 instead of 4.5.3 and use binutils 2.24 2014/1/10 Salman Sheikh > Now in that misoc/README you referenced, it mentioned installing gcc...I > am attempting to do so but I don't find a gcc-core and gcc-g++ but just one > large (105MB) gcc file.

Now in that misoc/README you referenced, it mentioned installing gcc...I am attempting to do so but I don't find a gcc-core and gcc-g++ but just one large (105MB) gcc file. I tried running configure and it complained about needing these before proceeding, do they need any special target options or just plain vanilla compile.. configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.

Re: [M-Labs devel] LM32 testbench files modelsim compile error
You should not be running "make sim_%"
the % in Makefile is a bit like * in shell.
it means it will catch any target starting with "sim_"
So for instance you could type : make sim_pipe1 or make sim_hello_world
In order to run the unit tests which are in test/unittests:
you can run make unittest
If then you, after all that, still have issues with your lm32 objcopy
not supporting the -O verilog backend you can modify the Makefiles as I
did over here:
https://github.com/fallen/lm32/blob/asid/test/unittests/Makefile#112
Quote :
%.vh: %.elf
@$(OBJCOPY) -O binary $< $@.tmp
@hexdump -Cv $@.tmp | awk 'BEGIN { FS=" " } ; { for (i = 2 ; i <
18 ; i++) { printf "%s ",$$i } ; print " " }' > $@
@$(RM) $@.tmp
instead of using the objcopy stuff, it works in my environment :)

What exactly do you need Modelsim for? If it's for speed, you may
want
to try Verilator, which is free and very fast - sometimes faster
than
Modelsim. If you do, please share your testbenches/compilation
scripts.
