Ahoj,

I am trying to build latest Freetz-NG (git clone from this repository; git describe --tags: ng24080-144-g24937eb92) for FritzBox 7113.

After make menuconfig, make fails with error: implicit declaration of function 'memcpy' [-Wimplicit-function-declaration].

Adding -Wno-error=implicit-function-declaration to FREETZ_TARGET_CFLAGS gets stripped away -- after a make run FREETZ_TARGET_CFLAGS is reset and my change is gone.

Here output of make -j1:

My system:

Artix GNU/Linux (rolling release),

OK, I could workaround all issues regarding gcc-kernel and binutils-kernel, but I do not know how to properly implement all in the build system: For some I had to manually edit files after a first make run:

Add the following patch file(s) into make/toolchain/kernel/binutils/patches/2.18/ and make/toolchain/kernel/gcc/patches/3.4/:

This is a well known "problem" of the new gcc14: https://gcc.gnu.org/gcc-14/porting_to.html
The FREETZ_TARGET_CFLAGS are flags for the TARGET (eg fritzbox) but binutils are tools running on the hostto build thing for target!
So changes for binutils are here: https://github.com/Freetz-NG/freetz-ng/blob/master/make/toolchain/target/binutils/binutils.mk (For the kernel there is another binutils binary in another path)
To test you could use make binutils or make binutils-distclean

Btw, you could use gcc14 for target files, but its not default because of many incompatible packages ;-) ee9ce7c

To test you could use make binutils

That specific one Succeeds (and it downloads and builds binutils 2.22, not 2.18).

But a subsequent make gives the same error.

(Can I somehow "force" the build system to use an older gcc version until this issue is fixed? CC=gcc-13 make seems to be ignored.)

Regards!

Its the gcc of your system

How to install an older GCC version I know.

But I still need to force the build system to use the older one, which will be installed besides the up to date one. (I cannot remove the up to date one because it is a dependency for other packages.)

But I need to tell the Freetz-NG buildsystem to actually use the older one. CC=gcc-13 make is ignored, and make binutils builds version 2.22, not version 2.18, which is the one that fails to build when doing make.

Much easier is to use another vm or system.
Check you PATH variable and put the path of the older gcc at begin, eg

echo $PATH
PATH="/tmp/gcc:$PATH"

Check you PATH variable and put the path of the older gcc at begin, eg

After "properly" installing GCC 13 (as a distribution package), the executable is at /usr/bin/gcc-13. Nothing to mess around with /tmp/ or /opt/, and PATH override would not work since /usr/bin/gcc is the default gcc.

That's why there usually is an environment variable which can override which executable to use as C compiler (can also hook distcc, ccache, or so, as the user wishes).

For Freetz-NG, I haven't found such an environment variable to manually specify the host C(XX) compiler to use, that actually works.

I think I will just abandon my try to compile Freetz-NG instead of setting up a chroot or virtual machine or manually (= not using distrubution package) putting some GCC somewhere.

Regards!

maybe other toolchain/tools things also do not work with gcc14

Yes; I solved the make binutils-kernel thing by adding to
make/toolchain/kernel/binutils/binutils.mk the following lines:

BINUTILS_KERNEL_CFLAGS += -Wno-error=implicit-function-declaration
BINUTILS_KERNEL_CFLAGS += -w

(the second one just optional to silence warnings as well),
but gcc-kernel fails with the same error

After doing a git pull, I get a more fundamental error binutils-2.18/libiberty/regex.c:127:61: error: missing binary operator before token "(":

Is this still a problem? it workes with my fedora 40 which has

gcc-Version 14.2.1 20240801 (Red Hat 14.2.1-1) (GCC)

OK, I managed to get further.

I applied the same changes also to toolchain-mipsel_gcc-3.4.6/gcc-3.4.6 and the error does now also goes away for GCC. But make gcc-kernel now fails with checking whether the C compiler (gcc -D_GNU_SOURCE -fno-stack-protector --std=c++03 ) works... no:

make gcc-kernel (after iterated run to compile everything else):

this error goes away.

New error arises, I will report next.

(And a lot of warnings.)

This now exceeds my knowledge.

OK, I could workaround all issues regarding gcc-kernel and binutils-kernel, but I do not know how to properly implement all in the build system: For some I had to manually edit files after a first make run:

Add the following patch file(s) into make/toolchain/kernel/binutils/patches/2.18/ and make/toolchain/kernel/gcc/patches/3.4/:

--- libiberty/md5.c	2024-09-09 17:03:04.889417535 +0200

-#  if defined STDC_HEADERS || defined _LIBC

#   include <stdlib.h>

Add the following to make/toolchain/kernel/gcc/gcc.mk:

TOOLCHAIN_HOST_KERNEL_CFLAGS += -Wno-error=incompatible-pointer-types

After a first make run, change line 1151 of source/toolchain-mipsel_gcc-3.4.6/gcc-3.4.6/intl/configure from
```
main(){return(0);}
```
to
```
int main(){return(0);}
```

Now, make kernel-binutils and make kernel-gcc do succeed with host GCC version 14.2.1.

@fda77, can you add those changes to the sources, and especially find a way to add 2. and 3. properly (for 2., I think a proper edit could be to adapt the sources to be more compliant, but that might be overkill work?, or, manually specify or download an older host GCC version?)?

Regards!
