我正在尝试在Linux(Ubuntu 18.04)上构建mailcore2库,但遇到了困难。 (通常)按照此处的回购指示进行操作: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存储库中的更新指令: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
但是无论我使用什么提交,我总是会遇到以下错误:

我已经在iOS上使用了一段时间(通过CocoaPods),但是想将我的电子邮件功能转移到服务器端。我在Github上打开了一个问题,但没有任何帮助。
答案 0 :(得分:1)
在/home/<USER>/mailcore2/build/src/include/MailCore/MCICUTypes.h
替换:
typedef __CHAR16_TYPE__ UChar;
具有:
typedef char16_t UChar;
然后运行:
make clean
make
