Compile with `--prefix` doesn't work

[scopatz]

I am using conda to build and install xbasic. However when I build with ./configure --prefix=/path/to/conda, make fails to recognize this and will error out because it can't find the readline headers:

do_gets.c:22:10: fatal error: readline/readline.h: No such file or directory
 #include <readline/readline.h>
          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.

The issue where this occurs is at conda-forge/staged-recipes#8509

Note that I think this is because the custom CFLAGS variable in the environment prior to the build is not being respected by the build system here

I have not heard about conda-forge so far. Let me check....

It can well be, that the CFLAGS from the environment is ignored. So this would be a mater of the Makefile. At the moment I have no clue...

[kollokollo]

Try following:

In Makefile.in:line 66

CFLAGS= @CFLAGS@ $(INC) $(DEF) $(OPT) $(REGS)

[kollokollo]

Maybe another line in the Makefile should be modified. I have attached a modified Makefile.in. I am not sure if this solves the issue. Need someone to test this.

Progress! Now it just fails to link against readline:

OK, here is a next try

I am now getting a lot further in the compilation, but now back to seeing:

do_gets.c:22:10: fatal error: readline/readline.h: No such file or directory
 #include <readline/readline.h>
          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Here is a gist with the build output

[kollokollo]

Yes, thanks, this is useful information, however, as far as I can see, readline is not the only package missing, e.g. lapack, and even X11 (X.org). The corresponding -dev packages need to be installed before trying to compile,e.g.
sudo apt-get install libreadline-dev, Xorg-dev, liblapack-dev etc...
At least on a normal Ubuntu one would do this.

[kollokollo]

Are you sure, that the intermediate state (where it compiled but not linked) was really successfull? Maybe you have not redone the ./configure after placing a new Makefile.in. If you just type make (after having touched the Makefile.in), a prefix of /usr/bin is used.

[kollokollo]

Is this still an issue, or can this be closed?
