linux - 在 Linux 上构建 Mailcore2

Question

我正在尝试在 linux(Ubuntu 18.04)上构建 mailcore2 库，但遇到了困难。 (大多数情况下)按照他们的 repo 说明:https://github.com/MailCore/mailcore2/blob/master/build-linux/README.md
所以首先我安装依赖项(一切正常):

sudo apt-get install libctemplate-dev libicu-dev libsasl2-dev libtidy-dev \
    uuid-dev libxml2-dev libglib2.0-dev autoconf automake libtool cmake

然后它指示如何构建 libetpan，但我使用的是 libtepan 存储库中的更新说明: https://github.com/dinhviethoa/libetpan :

git clone https://github.com/dinhviethoa/libetpan
cd libetpan
./autogen.sh
make
sudo make install

最后我尝试构建MailCore:

git clone https://github.com/MailCore/mailcore2
cd mailcore2
mkdir build
cd build
cmake ..
make

但无论我使用什么提交，我总是会收到以下错误:

我在 iOS 上使用它(通过 CocoaPods)已经有一段时间了，但想将我的电子邮件功能移动到服务器端。我在 Github 上打开了一个问题，但还没有吸引力。

在 /home/<USER>/mailcore2/build/src/include/MailCore/MCICUTypes.h代替:

typedef __CHAR16_TYPE__ UChar;

和:

typedef char16_t UChar;

然后运行:

make clean
make
