构建emacs ubuntu，找不到库

Question

我正在尝试安装emacs 26-1。当我运行./configure时，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，它们似乎已经存在。我尝试了很多东西，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

要么

:~$ 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？

Answer 1

为了完整，

# install essential build tools
sudo apt-get install build-essential

②下载emacs依赖项：

# get all dependencies of a previous emacs version
sudo apt-get build-dep emacs24


./configure
make

Answer 2

结束了

sudo add-apt-repository ppa:kelleyk/emacs
sudo apt-get update
sudo apt install emacs26
