[Help-bash] How to build bash with additional compiler flags?

[Peng Yu]

Hi,

I'd like to add the following compiler flags. Normally they should be
via the following standard flags

CFLAGS -finstrument-functions
LDFLAGS -Lsomedir_for_trace -Wl,-no_pie
LDLIBS -ltrace

Meanwhile, I want to keep -g but disable -O2.

However, bash does not seem to use the GNU Make variables in the
standard way. For example, it does not use LDLIBS. I tried with LIBS,
but it will not compile. I also played with CFLAGS_FOR_BUILD and
LDFLAGS_FOR_BUILD, but I can not get it to work.

$ ./configure CFLAGS=-g\ -finstrument-functions LDFLAGS=-Wl\,-no_pie\
-Lsomedir_for_trace LIBS=-ltrace
$ make

Does anybody know how to add these options?

Thanks.
