Virtuoso-7 fail to install on OS 10.15 with XCode 12.0

[JacquesLB]

virtuoso-7 is required by tellico.

Installation on a brand new MacBook Pro, with all Apple updates installed (Version 10.15.6, XCode 12.0) fails during compilation. Huge number of errors in the log file (see below). MacPort 2.6.3

This is way above by expertise to analyse.

I can reproduce the error:

My guess is that it is waiting until linking to use the stricmp() implementation from libsrc/util/stricmp.c, and isn't providing a header file to declare it.

In the future, please add the port maintainer(s) to Cc (port info --maintainers virtuoso-7), if any.

[JacquesLB]

Replying to mf2k:

In the future, please add the port maintainer(s) to Cc (port info --maintainers virtuoso-7), if any.

OK. Sorry.

[nerdling (Jeremy Lavergne)]

This might be a parallelism issue: you've got -j16 but it builds for me with -j4.

I'm trying to build without trace mode this time, too.

[nerdling (Jeremy Lavergne)]

Looks like the issue exists only without trace mode.

Can you try building with port -t to see if it's a workaround for whatever weirdness is being pulled in?

[JacquesLB]

I just tried that. Here is the output. Short answer: same.

Note: I am using bash 4.4 from MacPort as my shell (and not Apple new zsh). This is done thru "terminal" preferences: /opt/local/bin/bash -l However, I just notice that /private/var/select/sh is a symlink to /bin/bash Is there something behind?

Thank you for the efforts.

[JacquesLB]

No news?

I just tried again (after a port upgrade outdated). Same problems.

J.

[nerdling (Jeremy Lavergne)]

Right now, all I have is it builds for me with trace mode enabled. There is a build error without trace mode, and I'll need time to dig in and see what's being pulled in opportunistically—and make it stop.

[sharris40 (Spencer Harris)]

-Werror,-Wimplicit-function-declaration is a new default in Clang for Xcode 12. To fix it, you could just add the function prototype to an appropriate place via a patch. You could also just turn off the error, but then you'd be covering up the real problem.

[JacquesLB]

I'm glad you identified the origin. Unfortunately, I'm not skilled enough to understand your fix.

Thank you anyway. J.

[JacquesLB]

Any progress?

Jacques

[chrstphrchvz (Christopher Chavez)]

To correct myself, stricmp() is declared in libsrc/util/strfuns.h, so maybe #include "util/strfuns.h" (or possibly #include "libutil.h") is all that's missing from libsrc/Wi/numeric.c. I will try that and open a PR if it works.

[chrstphrchvz (Christopher Chavez)]

Still more errors to figure out:

virtuoso-7 is also a dependency for digikam. exactly the same problem noted as Jacques when trying to install digikam. trying the port clean, port install -t trick, but not expecting any luck.

[JacquesLB]

I just installed XCode 12.1. Still the same error. This is not too surprising if they changed a compilation "Warning" to an "Error". They would not revert that. Jacques

Any progress?

I submitted a fix for libsrc/Wi/numeric.c: ​https://github.com/openlink/virtuoso-opensource/pull/931

But at this point I'm inclined to give up and let someone use configure.cflags-append -Wno-error=implicit-function-declaration and/or see if upstream is interested in fixing this. There are even more errors (after working around the ones in comment:16) which I did not figure out how to work around:

Thank you for the effort.

Is it possible to pass the compilation options "configure.cflags-append -Wno-error=implicit-function-declaration " to MacPort when upgrading? Up to now I just use "sudo port upgrade virtuoso-7", which fails. But I am willing to try something more elaborate.

virtuoso-7: allow implicit function declarations

Closes: #61216

[kencu (Ken)]

just so we keep track...

I believe using this fix -Wno-error=implicit-function-declaration will mean it cannot build on arm64.

If that is true, we should perhaps mark all these somehow as we'll soon be back to fix them again (hopefully with upstream fixes.)

[jmroot (Joshua Root)]

Replying to kencu:

I believe using this fix -Wno-error=implicit-function-declaration will mean it cannot build on arm64.

Slightly worse than that; it will build, but if there are any cases where the implicit declaration does not match the actual function definition, then incorrect machine code will be generated for the call. That will most likely result in mysterious incorrect runtime behaviour. You might think you could just trust that all the implicit declarations are correct, but that's unlikely to be the case because implicit declaration is always ambiguous. It doesn't convey whether the function takes varargs, for one thing, and that changes how the arguments are passed with the arm64 ABI. That's why Apple changed this warning to an error.

tl;dr, if you turn off this error, you also need to disable building for arm64.

[JacquesLB]

Thank you everybody. virtuoso-7 installs without any problem now.

However, as mentioned in my first post, the aim was to install "tellico". Dependencies proceeded a bit further, and I stumbled on a similar problem with Building sane-backends:

:info:build scanimage.c:1229:42: error: implicit declaration of function 'basename' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
:info:build               png_set_iCCP(*png_ptr, *info_ptr, basename(icc_profile), PNG_COMPRESSION_TYPE_BASE, icc_buffer, icc_size);

Should I open a new ticket, or will somebody propagate the patch to other ports?

[JacquesLB]

My mistake. The ticket already exists:
