Hi
After cloning the latest build, I ma seeing below error
Linking...
Intel Math Kernel Library (MKL 11.3.3) and
Intel Integrated Performance Primitives (IPP 9.0.3) have been included

If you want to replace them into shared libs, do '-L PATH -lippi,' etc.

It is same issues in #7
Can you please follow up in that link?
I need to check
- There must be a static-linked library as RePlAce/module/verilog-parser/lib/libverilog-parser.a
- Whole compile log (for libverilog-parser.a)
I did follow the above link. I am seeing something strange this time
Before doing make in Replace directory, I am seeing the libverilog-parser.a

Replace make log:
Replace_make.log
Since I don't see the solution mentioned anywhere, I'll state it here: To get the verilog parser library requires cd'ing to modules/verilog_parser/src and doing "make libverilog_parser.a". That creates the modules/verilog_parser/lib directory and puts libverilog_parser.a there. However, this needs to be incorporated into the RePlAce make script somehow. . .
I also had to make a correction in verilog_parser.h to get it to work. Apparently on my system, "int" and "yy_size_t" are not the same length, resulting in "yy_scan_bytes" not being recognized when called. Fixing it required changing the extern line for yy_scan_bytes to "extern YY_BUFFER_STATE yy_scan_bytes (const char *bytes, yy_size_t len );"
Here is a list of things I needed to do to get RePlAce to compile:
(1) set environment variables MLKROOT and IPPROOT to point to the correct install location of the intel libraries in /opt/intel/.
(2) Change src/timingSta.cpp line 308 from "cout << std::defaultfloat;" to "cout.unsetf(std::ios_base::floatfield);". This is apparently a gcc limitation in implementing C++-11 which has (had) not been fixed as of gcc 4.9.2.
(3) Change src/global.h lines 388 and 440 from name("") to name({'\0'}). This is also some kind of gcc bug as it does not want to map a const char size 1 onto a field of const char size 255.
(4) Manually run "make libverilog_parser.a" in modules/verilog_parser
And. . . It compiles!
But, hey, will somebody add an "install:" target to the Makefile and perhaps make a nice wrapper script for the whole thing, as running "execute_lefdef.py" and "execute_bookshelf.py" is very non-intuitive.
From a few minutes of playing around with it, I think that it is only necessary to have an "install:" target that puts src/RePlAce into some standard location like /usr/local/bin/, which should be easy enough to add to the Makefile.
Hi guys
Thanks for your update. I still can't install on Ubuntu 16.04.5 with GCC 7.2.
I'm getting stuck at
./module/verilog-parser/lib/libverilog_parser.a(verilog_parser_wrapper.o): In function verilog::verilog_parse_string(char*, int)': /home/bku/work/git/asic/openroad/RePlAce/module/verilog-parser/src/verilog_parser_wrapper.c:49: undefined reference to yy_scan_bytes(char const*, int)'
The fix by @RTimothyEdwards is incorporated, but my linker still refuses to proceed.
I made a fork to update scripts, pls check it here: https://github.com/tetra12/RePlAce
@RTimothyEdwards could you pls validate my fork and advice on how to proceed ?
Thank you!
Note that the RePlAce source tree incorporates several other projects by recursive git. So as far as I can see, your fork does not incorporate the verilog parser, which is a separate github project in mgwoo/verilog_parser. I think you would need to fork that project separately and edit it, then change the recursive link.
But for your own error: You put " char const* " where it should have been " const char * ". Fixing that should fix the compile error.

Could you check below commit and comments for this problem?
mgwoo/verilog-parser@651b4c3
#7 (comment)
To avoid this problem, I've ported executable flex compiler in verilog-parser repository:
mgwoo/verilog-parser@cb940cf
Anyway, I thought using the Ben-marshall's verilog-parser is not a good Idea anymore.
It still has a limitation when parsing verilog files with delimiters (starts with \ and contains string /,[,]) and frequently generates these kinds of compile problem.
Could you recommend a good verilog-parser to use this project? I've already tried yosys and OpenSTA, but they are complicated and heavy. (and yosys was not able to handle some verilog statements.).
Thanks
