Compilation error: static declaration of 'sigaction' follows non-static declaration

[ulrivo]

On a fresh install, doing 'make sim' results in.

recorder.c:1997:20: error: static declaration of 'sigaction' follows non-static declaration

Hi @ulrivo, thanks for sharing.

Could you tell me what is the content of your config.h? It's weird that you are in the !HAVE_SIGACTION part of the code when you clearly have a sigaction definition.

Does that also happen if you directly go to the recorder and to a git clean -dfx; make?

Can you share the content of the file recorder/.logs/make.log?

[ulrivo]

My file recorder/config.h contains:

/* #undef HAVE_SIGACTION */
/* #undef HAVE_REGEX_H */
/* #undef HAVE_SYS_MMAN_H */
/* #undef HAVE_SIGNAL_H */
/* #undef HAVE_DRAND48 */
/* #undef HAVE_LIBREGEX */
/* #undef HAVE_SETLINEBUF */

Here is my file recorder/.logs/make.log:

make.log

After a git clean -dfx; make, I get

Hi @ulrivo, the Can you share the content of this file: /Users/ulrivo/dev/db48x/db48x/recorder/.build/macosx-clang/opt/CFGFNsigaction.c".err?

[c3d]

Also, what is the version of macOS and the SDK you are using?

[ulrivo]

macOS Sonoma 14.7

which SDK do you mean? Xcode? Version 16.1

The file /Users/ulrivo/dev/db48x/db48x/recorder/.build/macosx-clang/opt/CFGFNsigaction.c".err contains:

clang: error: unsupported argument 'armv7e-m' to option '-march='

[c3d]

The command line options in make.log are indeed quite strange. It looks like a rather unhealthy mix of native and cross compiler

-L/usr/local/opt/tcl-tk/lib  -mthumb -march=armv7e-m -mfloat-abi=hard -mfpu=fpv4-sp-d16

Does the /usr/local/opt/tcl-tk/lib path given to the -L option give you any hint? Does it pick that up from your environment?

In any case, if you are compiling on a mac, I would expect the command line to look something like this (one arg per line):

gcc
-lm
-lpthread
-framework CoreFoundation
-framework CoreServices
-Wl,-rpath,.
-Wl,-rpath,/Users/ddd/Work/calc/db48x/recorder/
-Wl,-rpath,/usr/local/lib/      "/Users/ddd/Work/calc/db48x/recorder/.build/macosx-clang/opt/CFGFNsigaction.c" -o "/Users/ddd/Work/calc/db48x/recorder/.build/macosx-clang/opt/CFGFNsigaction.c".exe

Your looks like this:

gcc
-L/usr/local/opt/tcl-tk/lib
-mthumb
-march=armv7e-m
-mfloat-abi=hard
-mfpu=fpv4-sp-d16
-Tsrc/dm42/stm32_program.ld
-Wl,-Map=build/dm42/release/db48x.map,--cref
-Wl,--gc-sections
-Wl,--wrap=_malloc_r
-lm
-lpthread
-lm
-lpthread
-framework CoreFoundation
-framework CoreServices
-Wl,-rpath,.
-Wl,-rpath,/Users/ulrivo/dev/db48x/db48x/recorder/ -Wl,-rpath,/usr/local/lib/       "/Users/ulrivo/dev/db48x/db48x/recorder/.build/macosx-clang/opt/CFGFNsigaction.c" -o "/Users/ulrivo/dev/db48x/db48x/recorder/.build/macosx-clang/opt/CFGFNsigaction.c".exe

So there is quite a bit of additional stuff.

As far as I can tell, none of this comes from teh make-it-quick build system. The most likely explanation is that you have CFLAGS or CXXFLAGS set that contains these values.

Can you show what env says in the environment where you build?

[ulrivo]

First: thank you very much for your effort to help me. Still not solved :-(

I assume that the -march=armv7e-m, -mfloat, -mthumb, -mfpu.. options are needed to compile for my Apple Silicon (M1) processor (??)

There were unwanted CPPFLAG and LDFLAGS in my .zshrc export CPPFLAGS="-I/usr/local/opt/tcl-tk/include" which I removed.

Now I get a different error message:
