I installed LPRng, then to install ifhp I run: $ sh STANDARD_configure
then I run: $ make clean all
and had this error:
cc1: warnings being treated as errors

Hope to find some idea.
place = strlen(convert);
size_t strlen(const char *s);

It appears that 'strlen()' is not the STD-C strlen?
I don't understand. You mean that the compiler has a problem?
I think the compiler is just fine, but there is something in one of the
include files that is redefining 'strlen'.
If you want, call me at my office 858-874-6543 and I will have you go through some
What you see is something which we also had in LPRng: there are some macros (like strstrlen) that cause newer compiler to generate warnings, and the -Werror makes them to errors.
Try to edit src/Makefile and remove the -Werror from the CFLAGS= line, then those should only be warnings and you are able to compile. (or call configure with an explicit CFLAGS parameter like ./configure CFLAGS="-Wall -O2 -g"
You can also try to fix those issues if you prefer, those 4 issues should be solved by just replacing safestrlen with strlen.
(safestrlen checks for NULL first, but as those arguments are static buffers they cannot be NULL, so gcc warns). But I guess you will run over other issues in other files.
I will surely verify Makefile and other include files, and post the result. Thanks Patrick and Brl. bye Mat
Oh, yes, safeSTRxxxx… This was done when a whole slew of libraries started to return
Null (char *)0 values… And boy was I ever glad I did this. Now we have the situation
where we have a compiler level test always failing. I suggest you simply change the
safestrlen to strlen at the places where the compiler is failing. I do NOT suggest you turn
I have done this in other places where this problem has occurred and feel that this is the
correct/safe way to do this.

I give up. I need to understand more things before. Thanks again , anyway.
Maybe in next future.
