Arch Linux User Repository

Not all apps are compatible with original 7-zip binaries!
In case of problems, try reverting to original p7zip.

I would like to install this package ... I think it is the most complete? also contains a gui? however there are a lot of p7zip dependencies ...

@Hanabishi thanks for the help.
I have permissions and ownership, and I also changed the line in the PKGBUILD, but it still gives the same error.
The 7-zip package works so I'll just use that, but thanks!

@calcium, well, check that you have permissions and ownership for the package directory.

Also try to edit PKGBUILD, change this line:

chmod -R a=r,a+X,u+w .

to

chmod -R a=rw,a+X .

and see does something changed.

The package doesn't build, I get this error:

make: g++: Permission denied
make: *** [../../7zip_gcc.mak:399: /home/yfoow/7-zip-full/src/build/StreamBinder.o] Error 127
make: Leaving directory '/home/yfoow/7-zip-full/src/CPP/7zip/Bundles/Alone'
==> ERROR: A failure occurred in build().

To build without ASM (uasm), set NO_ASM variable. For example:

NO_ASM=1 makepkg -si

@ZhangHua, I implemented your request, but in slightly different way.
Now the package can be built for all supported architectures and with clang.

Hello, I think this patch will allow this program to build under arm64 and x86 arch and with clang and gcc compiler, please consider merging it:

Checked with the custom flags and its seems ok. Here is an update with a respective patch.

@saltedcoffii, if you look at PKGBUILD you can see it has nothing to do with CFLAGS. They are baked in the source makefiles.
I can patch the source to respect custom CFLAGS, but can't say is this a good idea or not. Backed flags are very specific and obviously have some intentions by the developer.

7-zip-full does not respect custom CFLAGS specified in /etc/makepkg.conf. I have the following CFLAGS set:

CFLAGS="-march=x86-64-v2 -O3 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection -mpclmul"

The compiler invocation (the first one) is as follows:

gcc      -O2 -c -Wall -Werror -Wextra -Waddress -Waddress-of-packed-member -Waggressive-loop-optimizations -Wattributes -Wbool-compare -Wbool-operation -Wcast-align -Wcast-align=strict -Wcomment -Wdangling-else -Wdiv-by-zero -Wduplicated-branches -Wduplicated-cond -Wformat-contains-nul -Wimplicit-fallthrough=5 -Winit-self -Wint-in-bool-context -Wint-to-pointer-cast -Wunused -Wunused-macros -Wconversion   -DNDEBUG -D_REENTRANT -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC -Wno-maybe-uninitialized  -o /home/saltedcoffee/Projects/7-zip-full/src/build/7zStream.o ../../../../C/7zStream.c

If this is an issue with upstream, not with the PKGBUILD, let me know and I'm happy to report it.
