This is a list of non-linux systems that had no problems compiling and running or1ksim. You can report your success or failure to lampret@opencores.org and it will be included in here. Thanks again to all testers. -- Hi, I've read on opencores.org, you wanted to test or1ksim on other unix platforms. The only problem I encountered was in the makefile: @if [ Makefile -nt $(SIM_NAME) ]; then make distclean; fi; It didn't recognise the option -nt. Besides this I found no problems in compiling and running. It's not much, but I hope it helped. Here's a partial dump of version: Machine hardware: sun4d OS version: 5.7 Processor type: sparc Hardware: SUNW,SPARCserver-1000 The following components are installed on your system: Sun WorkShop University Edition 5.0 Sun WorkShop Compiler C 5.0 Sun WorkShop Compiler C++ 5.0 ... The worshop compiler complains about const. This should fix it: #ifndef const #define const #endif The gcc version 2.8.1 compiles fine. Kind regards, Marc Palmans
