compilation failed

[mauric]

Hi,
I have an issue with the compilation process. After clone the repo, and go to /src and made "make" there is a kind of references problem. I saw the code but I did not find any problem. So I don't know what its going wrong.
I have this message in my terminal

cc -c -o cr_main.o cr_main.c
cc -c -o cr_gpri.o cr_gpri.c
lex -t cr_lex.l > cr_lex.c
cc -c -o cr_lex.o cr_lex.c
cr_main.o: In function cr_add_regexp': cr_main.c:(.text+0x125f): undefined reference tocr_clear_marker_flags'
cr_main.o: In function main': cr_main.c:(.text+0x1401): undefined reference tocr_clear_marker_flags'
cr_main.o: In function cr_disp_line': cr_main.c:(.text+0x2c1d): undefined reference tocr_same_colors'
collect2: error: ld returned 1 exit status
Makefile:8: recipe for target 'hl' failed
make: *** [hl] Error 1
rm cr_lex.c

Thanks..

Hi,

what OS are you using (Linux, AIX, HP-UX, Solaris, BSD, ...) ? What
version / release ? What version of lex/flex ? What version of C compiler ?
Thanks.

Sorry, I forget that.

I'm using
Kunbuntu 15.10
KDE plasma 5.5.3,
Kernel Version 4.2.0-25 generic, 64bit.
Flex version flex 2.5.39 and
gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2)

It seems that the "inline" keyword is the origin of the problem.
Remove it from the file "cr_main.c" each time it appears (see the definitions of the functions cr_clear_marker_flags() and cr_clear_marker_flags() ), and recompile using "make".
It should be better.

Since I had no feedback from you, I close the issue.

Hi, I am using Ubuntu 16.04 (gcc 5.4) with the same error. Your solution worked fine! Thank you.

By the way, why you have to put double pipes in this command: ./hl -V || : in your makefile?

Hi,
I've just seen I haven't answered your question, sorry for that.
The double pipe '||' is an OR operator for the shell. The command following the '||' is executed if and only if the command before the '||' fails, i.e. if it returns false, which in shell language is a non-zero return code. When -V is passed to hl, the command returns a non-zero return code. Here, the command following the '||' is ':', which is another name for 'true', which always returns true. That way, the command ./hl -V || :always returns true, and so make doesn't stop its execution because of an error.
