it3q 0 Report post Posted September 24 Hi! I'm trying to compile and install systemC 2.3.3 using clang on cygwin.

Roman Popov 72 Report post Posted September 25 Clang 8 is quite new compiler and SystemC 2.3.3 was not tested against it. Do you see this issue only in Cygwin? Or in general with Clang 8, including Clang 8 on MacOS / Linux ? Quote Share this post Link to post Share on other sites
it3q 0 Report post Posted September 25 Right now I don't have the opportunity to check Clang 8 on other OS. I tried to compile with Clang 5.0.1 on cygwin. The same test failed as with Clang 8. May be cygwin issue, but cygwin's GCC version 7.4.0 compiles systemC that then passes all tests. I use cygwin 64 bit version 3.0.7 P. Quote Share this post Link to post Share on other sites
Philipp A Hartmann 240 Report post Posted September 25 Can you run the failing test manually in a debugger and provide more details on the error? The log looks truncated, as if there is a crash in the test. Quote Share this post Link to post Share on other sites

Philipp A Hartmann 240 Report post Posted September 25 10 minutes ago, it3q said: [Inferior 1 (process 13360) exited with code 0103] Exit code 0x103 could indicate an "illegal instruction". Can you try building SystemC with --disable-optimize? As Roman mentioned earlier, Clang 8 is pretty new and SystemC has never been tested with Clang on Windows.

it3q 0 Report post Posted September 25 test.exe debugged above was built by clang 5.0.2. Having configured with --disable-optimize and compiled with clang 5 resulted that all tests passed. In case of clang 8.0.1 test.exe (reset_signal_is test) exited with the same (0103) code. When I added --disable-optimize to configure 'make check' fails at the same test (reset_signal_is) but with different exit code: 05400. What do you recommend? Is it worth to use clang 5 compiler with optimization disabled or better if I stay with gcc? (My main motivation of using clang was to reduce compilation times of SystemC based simulations.) P.

Roman Popov 72 Report post Posted September 25 Clang 5 works fine for me on Linux. This may be a combination of Clang + Cygwin. Quote (My main motivation of using clang was to reduce compilation times of SystemC based simulations.) According to benchmarks https://www.phoronix.com/scan.php?page=article&item=gcc-clang-2019&num=4 compilation time difference for most projects is within 10%.
