在OSX 10上安装Alien::wxWidgets失败

Question

它基本上与this one相同，但并没有真正结束。

我正面临着同样的问题，我走得更远。我不得不修改代码以允许更新的Macos sdk (10.11)。因此，它编译了一段时间，但随后失败了，并显示以下内容：

❯❯❯ perl build

奇怪的是，当我检查配置日志时:这个(./wxWidgets-3.0.2/bld/src/tiff/config.log)有除lzma之外的其他错误，例如：

configure:18047: checking for lzma_code in -llzma

configure:18307: $? = 1

See the full version。

这与./wxWidgets-3.0.2/bld/config.log大同小异。

当我修改代码以允许os10.10SDK时，它之前期望的版本是10.8或者10.9。我想现在整个问题都是从这个开始的。我应该尝试获取一个旧的MacOS SDK吗？

基本上，我只想从源代码编译Slic3r --gui，这需要Wx，这需要wxwidgets。

Answer 1

这里的问题是，libtiff configure在/usr/local下检测到lzma.h，因为它没有使用-isysroot，但是它的编译使用了SDK选项，并且找不到它。正确的做法是在wxWidgets配置中显式地使用-I/usr/local/include，但是现在您应该能够通过执行export CPATH=/usr/local/include LIBRARY_PATH=/usr/local/lib来绕过它来解决这个问题。

或者(最好是)使用brew install tiff jpeg png (不确定公式名称是否正确，请检查它们)，以避免在一开始就构建这些库的内置版本。

Answer 2

运行brew install xz为我修复了这个问题。
