|
|
nuitka --show-scons --show-progress GNSS_start.py
|
|

4. 手动执行编译命令（Nuitka 用 @"./@link_input.txt" 这种方式把所有要链接的对象文件列表放在一个文本文件里，而不是直接写在命令行上）
|
|
cd GNSS_start.build/（@link_input.txt在当前目录下，如果从来没有相应的build文件夹，可执行nuitka GNSS_start.py或nuitka --generate-c-only GNSS_start.py）
|
|
gcc -o /root/GNSS_emb/GNSS_start.bin -flto=8 -fuse-linker-plugin -fpartial-inlining -freorder-functions -O2 -s -z noexecstack -Xlinker -export-dynamic -rdynamic -Wl,-rpath=/usr/lib -Wl,-R,'/usr/lib' -Wl,--disable-new-dtags -Wl,-b -Wl,binary -Wl,./__constants.bin -Wl,-b -Wl,elf64-littleaarch64 -Wl,-defsym -Wl,constant_bin_data=_binary_____constants_bin_start @"./@link_input.txt" -L/usr/lib -ldl -lm /usr/lib/python3.8/config-3.8-aarch64-linux-gnu/libpython3.8-pic.a -lz -lm -lutil -lpthread -lexpat
|
|
报错：
|
|
collect2: fatal error: ld terminated with signal 11 [Segmentation fault]
|
|
compilation terminated.
|
|
|
|
5. 对比编译正确的命令：
|
|
nuitka --show-scons --show-progress GNSS_start.py --lto=no
|
|
gcc -o /root/GNSS_emb/GNSS_start.bin -fno-lto -s -z noexecstack -Xlinker -export-dynamic -rdynamic -Wl,-rpath=/usr/lib -Wl,-R,'/usr/lib' -Wl,--disable-new-dtags @"./@link_input.txt" -L/usr/lib -ldl -lm /usr/lib/python3.8/config-3.8-aarch64-linux-gnu/libpython3.8-pic.a -lz -lm -lutil -lpthread -lexpat
|
|
|
|
6. 结论
|
|
--lto影响链接成exe，所以应该使用 --lto=no 选项去掉lto优化，完整命令应该是：
|
|
nuitka GNSS_start.py --lto=no
|
