Missing math library when linking gsi

[vonbrand]

Fedora 36 x86_64, at e98430b. After running ./config.status, make gives:

[gambiteer]

Thank you. Can you tell us the output to

./configure
rm -rf boot gsc-boot
make core

Thanks.

OK, I see the same thing on Ubuntu 22.04:

I'll look into things some more later.
Edit: adding -lm to the end of the command line erases this failure.

OK, I just did

    13	11:31	./configure
    14	11:31	rm -rf boot gsc-boot
    15	11:31	make core

and it failed earler:

Marc: Do we need to run autoconfig again?

[feeley]

I haven't yet had time to look into this in depth. My understanding is that the configure script thinks that the -lm C compiler option is not required to compile programs that need the math library. However, it seems that on some linux systems it is (now) required.

The immediate solution is to configure Gambit by explicitly using this flag, for example

configure --enable-single-host CC="gcc -lm"

[gambiteer]

No, that doesn't work:

gcc -lm -Wno-unused -Wno-write-strings -Wdisabled-optimization -fwrapv -fno-strict-aliasing -fno-trapping-math -fno-math-errno -fschedule-insns2 -foptimize-sibling-calls -fomit-frame-pointer -march=native -fPIC -fno-common -mpc64    -Wno-unused -Wno-write-strings -Wdisabled-optimization -fwrapv -fno-strict-aliasing -fno-trapping-math -fno-math-errno -fschedule-insns2 -foptimize-sibling-calls -fomit-frame-pointer -march=native -fPIC -fno-common -mpc64   -rdynamic  -I"../include"  -o gsi    _gsi.o _gsi_.o "../lib/libgambit.so"  libgambitgsi.so

But I really have to idea what's going on: Configuring with

./configure LDFLAGS='-lm' '--enable-march=native' '--enable-dynamic-clib' '--enable-single-host' '--enable-multiple-versions' '--enable-shared'

leads to:

The internets say that the -lm needs to go at the end.

The script that's invoked with gsc -exe will need to be updated, too.

[gambiteer]

This is a workaround:

./configure LIBS='-lm' '--enable-march=native' '--enable-dynamic-clib' '--enable-single-host' '--enable-multiple-versions' '--enable-shared'

[bheesham]

Potentially related: I ran into a similar thing here. I documented some steps to reproduce here: https://gist.github.com/bheesham/3235211d11935c94be09d31810350593

[feeley]

I believe this issue is due to a problem with recent versions of autoconf, and that autoconf 2.69 solves the issue. Please check 9abb138.

Could someone check if this solves the issue?

[gambiteer]

Yes, it's fixed.

[thchha]

Beeing on: 342399c7 (HEAD -> master, origin/master, origin/HEAD) SRFI 231: Improve testing.
Running: 6.5.0-1-arm64 #1 SMP Debian 6.5.3-1 (2023-09-13) aarch64 GNU/Linux
GCC: 13.2.0

I encountered the same error.
The workaround had still to be employed:

$ rm -rf boot/ gsc-boot/
$ ./configure LIBS='-lm' --prefix=/home/tomes/runenv/gambit --enable-single-host --enable-targets= --enable-bignum --enable-ratnum --enable-poll
$ make bootstrap; make bootclean; make -j8; make check; make modules; make install

The issue appears to persist.
Apparently the debian maintainers did the following to resolve the issue; Maybe this is of interest:
https://sources.debian.org/patches/gambc/4.9.3-1.2/autoconf2.71.patch/

[gambiteer]

I don't know much about configure, but the Debian patch:

 
 if test "$ENABLE_CPLUSPLUS" = yes; then
 
-  AC_LANG(C++)
+  #AC_LANG(C++)
   AC_PROG_CXX
   AC_PROG_CXXCPP
   C_COMPILER=$CXX

appears to kick in only when --enable-cplusplus is part of the configure command, and that doesn't seem to be the case in your configuration command.
Am I missing something?
And, I'm curious, was that patch applied across several (or many) packages? I can't imagine that this problem is unique to Gambit.

[thchha]

Sorry, You are absolutely right. I did not carefully read about the patch and referred to something not carefully inspected. I am not able to say if this patch was applied across different packages. It makes sense that this would be a problem across multiple programs linking to the math library.
May I be of assistance?

I just build and installed gambit on a new system and made sure I am on a commit which incorporates the linked fix. The error is relevant to me and the workaround was still required.

I am unable to interpret the changes on the file ./configure. Sorry.

[gambiteer]

Well, I have to apologize, I should have tried it before commenting, because it does fix the problem, but I have no understanding why.

Marc, do you want to put this in, maybe without fully understanding it?

[gambiteer]

I just tested the debian "fix" with --enable-cplusplus, and it works.
So it works with and without --enable-cplusplus.

[gambiteer]

I'm going to install the Debian patch soon unless I hear otherwise.

[thchha]

I compared the ./configures with/-out --LIBS='lm' but I couldn't make sense of it so I omitted a reply.

I don't understand this either. Why is asin declared as char asin() on the left?

After removing AC_LANG(C++) from configure.ac, running autoconf to rebuild configure, and everything worked fine with and without --enable-cplusplus.

[thchha]

I compared the ./configures with/-out --LIBS='lm' but I couldn't make sense of it so I omitted a reply. The left side shows the file when the workaround-argument is supplied. The right side appears to me as a hobby enthusiast to be c++ reliant.

What do you mean "when the workaround-argument is supplied"? What's the "workaround-argument"?

$ rm -rf boot/ gsc-boot
$ ./configure LIBS='-lm' --prefix=/home/tomes/runenv/gambit --enable-single-host --enable-targets= --enable-bignum --enable-ratnum --enable-poll

After running this my configure looks like the left side.
Omitting LIBS='-lm' results in the right side.
By configure, i mean the literal file within the root of the project.

  if test "$ENABLE_CPLUSPLUS" = yes; then                                                      |  if test "$ENABLE_CPLUSPLUS" = yes; then

I did not want to imply anything. I just noted that without supplying the LIBS=...-argument, my ./configure (after deleting the directories beforehand) look like the right side.

     Use char because int might match the return type of a GCC                               |    extern "C" int asin ();
     builtin and then its argument prototype would still apply.  */                          |  }

If I can assist, let me know.

I don't understand this either. Why is asin declared as char asin() on the left?

I am unable to make sense of it either. I just wanted to leave my last attempt so that maybe someone has an idea.

After removing AC_LANG(C++) from configure.ac, running autoconf to rebuild configure, and everything worked fine with and without --enable-cplusplus.

As long as it works across the supported operating systems it should be fine then.
