我尝试从源代码编译 surf 浏览器，但收效甚微。看来我错过了 gcr-3.pc。
编辑：我在 Ubuntu 19.04 上
c99 `pkg-config --cflags x11` `pkg-config --cflags gtk+-3.0 gcr-3 webkit2gtk-4.0` -DVERSION=\"2.0\" -DWEBEXTDIR=\"/usr/lib/surf\" -D_DEFAULT_SOURCE -DGCR_API_SUBJECT_TO_CHANGE -fPIC -O -c common.c
Package gcr-3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gcr-3.pc' to the PKG_CONFIG_PATH environment variable
echo $PKG_CONFIG_PATH 什么都没打印。我已经安装了 pkg-config ( pkg-config is already the newest version (0.29.1-0ubuntu2))，那么我应该在哪里获取它？在其他发行版论坛上阅读有关 pkg-config 的信息显示它应该在 /usr/lib/pkgconfig 中，但我只有一个文件，ibus-table.pc
而且，surf.c:8:10: fatal error: glib.h: No such file or directory
但我确实有glib！
>> cd /usr/include/glib-2.0
>> ls -a
. gio glib.h glib-unix.h gobject
.. glib glib-object.h gmodule.h
我真的很恼火，找不到任何列出编译 surf 的依赖项的文档，甚至 surf 的自述文件也只是说“您需要 GTK+ 和 Webkit/GTK+ 头文件”。我想我已经找到了，为什么什么都不起作用？我甚至还没有修改任何东西！
完整的 make 输出（包含大量有关类型的警告）：
>> sudo make clean install
rm -f surf surf.o common.o
rm -f libsurf-webext.so libsurf-webext.o

我在 make-ing 之前手动安装了所有这些依赖项：
build-essential
pkg-config
libglib2.0-dev
libgcc-4.8-dev
libseed-gtk4-dev
libgtk-3-dev
webkit2gtk-4.0

在终端中，运行sudo apt update && sudo apt install libgcr-3-dev<-- 即适用于 Ubuntu 18.04 LTS。您没有说您使用的 Ubuntu 版本是什么。
