请问怎么链接package中的静态库呢？ #2155

想要链接自定义的静态库，发现生成的命令不能通过编译，一些函数提示未定义

gcc 9.4

试过add_links, add_ldflags 都不行。target设置：

target("ch2")
    set_kind("binary")
    add_files("toyc.cpp", "parser/*.cpp", "mlir/*")
    add_includedirs("include")
    add_packages("llvm-mlir")
    add_rules("tblgen")
    platform_args()
    before_build(function(target)
        import("compile.tblgen")
        tblgen(target, "include/toy/Ops.td", "toy/Ops.h.inc", {"-gen-op-decls"})
        tblgen(target, "include/toy/Ops.td", "toy/Ops.cpp.inc", {"-gen-op-defs"})
        tblgen(target, "include/toy/Ops.td", "toy/Dialect.h.inc", {"-gen-dialect-decls"})
        tblgen(target, "include/toy/Ops.td", "toy/Dialect.cpp.inc", {"-gen-dialect-defs"})
    end)

生成的链接命令：

/usr/bin/g++     \

使用cmake重新定义工程，生成的链接命令，可以正确编译：

add_packages("llvm-mlir")

对应的 add_requires("llvm-mlir") 在哪呢？另外，llvm-mlir 这个包 xmake-repo 没收录，你自己仓库定义了？

看你给的命令，add_packages 不都生效了么。。links 也都加上了

如果顺序对，缺的符号，自己补 links

令不能通过编译，一些函数提示未定义

自己排查下 links 直接依赖顺序，package("llvm-mlir") 里面通过 add_links 固定下依赖顺序

似乎不是顺序问题，我把可以链接的命令中的全路径改成了跟xmake生成的同样的-l形式，是同样的顺序，这样不能通过编译

undefined reference to `pthread_sigmask'

这不是很明显了么，缺什么补什么。。add_syslinks("pthread")
