在 Ubuntu 上构建 Emacs - 找不到库

Question

我正在尝试安装 Emacs v. 26.1。当我运行时./configure，我看到以下错误：

configure: error: The following required libraries were not found:
    libXpm libjpeg libgif/libungif libtiff gnutls
Maybe some development libraries/packages are missing?

然而，他们似乎已经在那里了。我尝试了多种方法，例如：

: ~$ apt-cache search gnutls
gnutls-doc - GNU TLS library - documentation and examples
libcurl3-gnutls - easy-to-use client-side URL transfer library (GnuTLS flavour)
libcurl4-gnutls-dev - development files and documentation for libcurl (GnuTLS flavour)
libgnutls-openssl27 - GNU TLS library - OpenSSL wrapper

和

:~$ sudo apt install libcurl4-gnutls-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libcurl4-gnutls-dev is already the newest version (7.58.0-2ubuntu3.6).
0 to upgrade, 0 to newly install, 0 to remove and 11 not to upgrade.

事情似乎很好。我错过了什么？

如错误消息中所述，您实际上需要这些库的开发版本（在Ubuntu 19.10 (Eoan Ermine)上使用 Emacs v. 27 测试）：

sudo apt install libxpm-dev libjpeg-dev libgif-dev libtiff-dev libgnutls28-dev
