在Linux上构建Mailcore2 [英] Building Mailcore2 on linux

问题描述

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

I'm trying to build the mailcore2 library on linux (Ubuntu 18.04) but having a hard time. (Mostly) following the directions on their repo here: https://github.com/MailCore/mailcore2/blob/master/build-linux/README.md

所以首先我要安装依赖项(一切都很好):

So first I install dependencies (that all goes fine):

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 :

Then it instructs how to build libetpan, but I'm using the updated instructions from the libtepan repo: 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:

Finally I try to build 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:

But no matter what commit I'm using, I always get the following error:

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.

I've been using it on iOS (via CocoaPods) for a while, but wanted to move my email functionality to the server-side. I opened an issue on Github, but no traction yet.

推荐答案

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
