yocot 开发问题集结
做yocto的linux项目，使用gdb的时候一直提示，no debugging synbols found
这个在网上说是在编译的时候要添加-g，但是我已经在makefile里添加了还是不行，后来看google，yocto项目需要添加gdb 的package才能显示：
EXTRA_IMAGE_FEATURES += "\
dbg-pkgs \ # adds -dbg packages for all installed packages and symbol information for debugging and profiling.
tools-debug \ # adds debugging tools like gdb and strace.
tools-profile \ # add profiling tools (oprofile, exmap, lttng valgrind (x86 only))
tools-testapps \ # add useful testing tools (ts_print, aplay, arecord etc.)
debug-tweaks \ # make image for suitable of development, like setting an empty root password
tools-sdk \ # OPTIONAL: adds development tools (gcc, make, pkgconfig, etc)
dev-pkgs" # OPTIONAL: adds -dev packages for all installed packages
# Specifies to build packages with debugging information
DEBUG_BUILD = "1"
# Do not remove debug symbols
INHIBIT_PACKAGE_STRIP = "1"
# OPTIONAL: Do not split debug symbols in a separate file
INHIBIT_PACKAGE_DEBUG_SPLIT= "1"
2. ERROR: taskset-1.0-r0 do_package: QA Issue: File '/usr/bin/taskset' from taskset was already stripped, this will prevent future debugging! [already-stripped]".
Re: adding pre-built application to roots
Actual solution was to add this strings to project-spec/meta-user/recipes-apps/taskset/taskset.bb:
INSANE_SKIP_${PN} = "ldflags"
INHIBIT_PACKAGE_DEBUG_SPLIT = "1"
INHIBIT_PACKAGE_STRIP = "1"
3.QA Issue: -dev package contains non-symlink .so:
non -staticdev package contains static .a library:
添加的软件包中引用了static 库，所以需要在bb文件中添加static的引用声明
FILES_${PN}-staticdev ="" # for static libs
FILES_${PN}-dev ="" # for dynamic libs
FILES_${PN}-dbg ="" # for debug optionsFILES_${PN}-staticdev += "/usr/lib/python3.8/config-3.8-arm-linux-gnueabi/*.a"
4.do_package_qa: QA Issue: -dev package contains non-symlink .so
在bb文件添加：INSANE_SKIP_${PN}-dev += "dev-elf"

在相应的路径上添加如下代码即可
FILES_${PN}-dev += "/usr/lib/*.so"
FILES_${PN}-dev += "/usr/lib/atlas-base/*.so"
FILES_${PN}-dev += "/usr/lib/atlas-base/atlas/*.so

9. Unescaped left brace in regex is illegal here in regex; marked by <– HERE in m/${ <– HERE ([^ \t=:+{}]+)}/ at xxx line xxx
原因
原因是Perl不支持以前的写法。
解决方法
编辑提示的文件xxx的行号xxx
例如 /usr/bin/automake 第 3930 行
将 -$text =~ s/\${([^ \t=:+{}]+)}/substitute_ac_subst_variables_worker ($1)/ge;
修改为 -$text =~ s/\$[{]([^ \t=:+{}]+)}/substitute_ac_subst_variables_worker ($1)/ge;
