ZSNES 1.4 refuses to compile (now Illegal Instruction!!??)

kyo-KUSANAGI · Post by **kyo-KUSANAGI** » Sun Dec 26, 2004 9:13 am

Just like to thank everyone on the ZSNES team for making a non-Christmas-present receiver happy on Christmas day, but I am sorry to report that it just refuses to compile on Gentoo 2004.2 (doesn't mean much, updated almost every package already). I can run ZSNES 1.36 already on my system (2.6.9-gentoo-r9), compiling ZSNES 1.40 gives me this:

yeah. Is this supposed to happen or what, cause I don't see many people complaining about this.

SORRY! looks like I was following instructions on the DOS part of the install.txt.

Look in the docs directory for instructions on what your supposed to do.

Trying to compile the DOS port under Linux is not what you should be doing to build a working Linux binary.

thanks for the pointer, nach, however, I ran into another obstacle:

Illegal instruction

The window appears for a while, but when I type something, or move my mouse within it's boundaries, it terminates with the "Illegal instruction" error. No other messages to work on.

It sounds like you compiled for an architecture your PC doesn't support. Like Pentium4 optimizations, but you only have a PIII.

I have a VIA C3 (Ezra).
I didn't tell the compiler anything funky. Just typed in sh ./autogen.sh && gmake && gmake install. Anything specific I should do for this processor?
ADD: you know, while browsing through config.status, I came across an instance of "-march=pentiumpro". I replaced that with -march=c3, but that didn't work, because later on, while it was compiling, I found a lot of "pentium" strings showing up. Might that be it? Probably your scripts are assuming that my processor is a C3.

Which -march did you compile with?

kyo-KUSANAGI · Post by **kyo-KUSANAGI** » Sun Dec 26, 2004 1:14 pm

As I said, I didn't specify any march (but I did try changing the one in config.status to a "c3" from a "pentiumpro"). However, in my /etc/make.conf (it's a gentoo distro) I specified a CFLAG as -march=c3, but because I didn't use portage to emerge this, that CFLAG probably went unused.

To be honest, I have no idea what you're talking about.

When you run make in your source directory now, you should see something like this:

Code: Select all

gcc  -pipe -I. -Wall -I/usr/local/include -I/usr/include -D__LINUX__  -I/usr/include/SDL -D_REENTRANT  -D__OPENGL__ -O3 -ffast-math -fomit-frame-pointer -fexpensive-optimizations -s -march=pentiumpro -o version.o -c version.c

I'm not sure which -marchs your proccessor is compatible with, but one specific for your proccesor or i686 should work fine.
Change it by editing Makefile, then do
make clean
make

kyo-KUSANAGI · Post by **kyo-KUSANAGI** » Sun Dec 26, 2004 3:15 pm

/etc/make.conf has global options for gcc inside it. So, for instance, if you put CFLAG= -m3dnow, simply typing gcc would mean to the computer "gcc -m3dnow". I think

Last point of clarification: there are a lot of makefiles in the zsnes_140/src directory. Which one do you mean?
bash-2.05b# ls makefile*
makefile.dos makefile.mingw makefile.win
bash-2.05b# ls Makefile*
Makefile.check Makefile.in
bash-2.05b#

I mean the one called "Makefile", it should be created after running autogen.sh

Tip.

CFLAGS="-march=c3" ./autogen.sh

I did that with gentoo, and...it works. :p
