Waf - 找不到本地dll

Question

我正在尝试将makefile从另一个构建系统转换为waf。

我正在尝试将waf指向包含必要dll的目录。

但是，在运行waf configure时：

Checking for library libiconv2           : not found

找不到所需的库。

Answer 1

你只是缺少use变量设置，但这必须在你的孩子的脚本中修复，即

bld.program (...,
    libpath = ['/usr/lib', 'subpath'], #this has to be relative to the wscript it appears in! (or the root wscript, can not recall)
    ...,
    use = ['iconv2', 'regex2'] )

参见waf book

的第9.1.2节

---

另外：（可能是更干净的版本）

cfg.check_cc(lib='iconv2', uselib_store="LIBICONV2", mandatory=True)

然后将uselib与

一起使用

bld.program (...,
    libpath = ['/usr/lib', 'subpath'], #this has to be relative to the wscript it appears in! (or the root wscript, can not recall)
    ...,
    uselib = ['LIBICONV2', ...] )

Answer 2

经过一番考虑后，我意识到我需要更多信息。 waf提供的默认错误信息似乎与waf本身有关，而不是wscripts或项目。

要解决此问题，需要添加记录器。我在配置和构建函数中添加了记录器。

配置记录器：

cfg.logger = Logs.make_logger("configure_%s.log" % datetime.date.today().strftime("%Y_%m_%d"), "configure")

构建记录器：

bld.logger = Logs.make_logger("build_%s.log" % datetime.date.today().strftime("%Y_%m_%d"), "build")

这样做可以让我了解问题的本质：

['C:\\MinGW64\\bin\\g++.exe', '-Wl,--enable-auto-import', '-Wl,--enable-auto-import', 'test.cpp.1.o', '-o', 'C:\\Users\\Administrator\\Downloads\\libpst-0.6.60\\clean\\build\\temp\\conf_check_5fe204eaa3b3bcb7a9f85e15cebb726e\\testbuild\\testprog.exe', '-Wl,-Bstatic', '-Wl,-Bdynamic', '-LC:\\Users\\Administrator\\Downloads\\libpst-0.6.60\\clean\\libs', '-llibiconv2']

err: c:/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/4.7.2/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:\Users\Administrator\Downloads\libpst-0.6.60\clean\libs/libiconv2.dll when searching for -llibiconv2

库路径已正确传递给gcc，但dll为 32位，而gcc安装为 64位，因此不兼容
