Unable to install without building shared library

[mylovesaber]

Prepare musl-gcc static version

musl-gcc:

cd ~
wget https://musl.libc.org/releases/musl-1.2.5.tar.gz
tar xfv musl-1.2.5.tar.gz
mkdir -p ~/musl-1.2.5/build
cd ~/musl-1.2.5/build
../configure \
--prefix=$HOME/musl \
--exec-prefix=$HOME/musl \
--syslibdir=$HOME/musl/lib \
--disable-shared
make -j$(nproc)
make install
cd ~

lz4 static build

Makefile

mkdir -p sources
wget -P ~/sources https://github.com/lz4/lz4/releases/download/v1.9.4/lz4-1.9.4.tar.gz
tar xfv lz4-1.9.4.tar.gz
cd lz4-1.9.4
make -j$(nproc) liblz4.a \
CC="musl-gcc -static" \
CFLAGS="-I/home/build/musl/include -O3" \
LDFLAGS="-Wl,--rpath=/home/build/musl/lib"

Everything works fine.

Then, I'm not able to install static build only. It always continue to build shared lib.
Am I ignore something?

CMake

Cmake always use GNU gcc from system instead of specified musl-gcc(It shows musl is ignored)

CC="musl-gcc -static" cmake -DCMAKE_INSTALL_PREFIX=/home/build/musl \
-DBUILD_SHARED_LIBS=OFF \
-DCMAKE_C_COMPILER=musl-gcc
# or
CC=/home/build/musl/bin/musl-gcc cmake -DCMAKE_INSTALL_PREFIX=/home/build/musl \
-DBUILD_SHARED_LIBS=OFF

the command above perform the same output.

Other info

System (please complete the following information):

• OS: fedora-server 38
• Compiler : musl-gcc(static)
• Build System Makefile

Hi @mylovesaber,

EDIT 2024-03-31 : This is a totally wrong answer. Please take a look next post.

Wrong answer

In my environment, I have no issue with musl-gcc. make liblz4.a just build static library.

cd
git clone --depth 1 --branch v1.9.4 https://github.com/lz4/lz4.git lz4-issue-1387
cd lz4-issue-1387

git log -1

Could you try make clean liblz4.a without CC, CFLAGS, LDFLAGS and observe the result?

Sorry. I misunderstand your issue. BUILD_SHARED, DESTDIR, and PREFIX settings will help you. For example:

rm -fR ~/mylz4-issue-1387-artifact
mkdir  ~/mylz4-issue-1387-artifact

cd
git clone --depth 1 --branch v1.9.4 https://github.com/lz4/lz4.git lz4-issue-1387

cd ~/lz4-issue-1387
make -C lib clean install BUILD_SHARED=no DESTDIR=~/mylz4-issue-1387-artifact PREFIX=

# make: Entering directory '/mnt/projects/lz4/lib'
# Cleaning library completed
# compiling static library
# creating pkgconfig
# Installing libraries in /home/user/mylz4/lib
# Installing headers in /home/user/mylz4/include
# lz4 libraries installed
# make: Leaving directory '/mnt/projects/lz4/lib'

tree ~/mylz4-issue-1387-artifact

# /home/user/mylz4-issue-1387-artifact
# ├── bin
# ├── include
# │   ├── lz4.h

note: Current version of lib/README.md#makefile-variables says it generates libzstd but of course this is a typo. Actually it will generate liblz4.
