我正在尝试在我的 x86 机器（VirtualBox 下的 Ubuntu 11.04）上为 arm 编译 gnutls。现在我一直在编译 libnettle。./configure脚本找不到 -lgmp 并在没有我需要的公钥加密（没有libhogweed ）的情况下生成荨麻。config.log中的消息如下：

对于 x86：

configure:6976: checking for __gmpz_getlimbn in -lgmp
configure:7001: gcc -o conftest -L"/home/xena/gnutls/out/x86/lib/"   conftest.c -lgmp   >&5
/usr/bin/ld: cannot find -lgmp
collect2: ld returned 1 exit status
configure:7001: $? = 1

对于 ARM：

configure:6976: checking for __gmpz_getlimbn in -lgmp
configure:7001: arm-none-linux-gnueabi-gcc -o conftest -L"/home/xena/gnutls/out/arm/lib/" -mcpu=arm926ej-s -mthumb   conftest.c -lgmp   >&5
/usr/local/codesourcery/bin/../lib/gcc/arm-none-linux-gnueabi/4.7.3/../../../../arm-none-linux-gnueabi/bin/ld: cannot find -lgmp
collect2: error: ld returned 1 exit status
configure:7001: $? = 1

这些库在那里：

xena@xena-VirtualBox:~/gnutls$ ls /home/xena/gnutls/out/x86/lib/ | grep libgmp
libgmp.a
libgmp.la
libgmp.so
libgmp.so.10
libgmp.so.10.1.2
xena@xena-VirtualBox:~/gnutls$ ls /home/xena/gnutls/out/arm/lib/ | grep libgmp
libgmp.a
libgmp.la
libgmp.so
libgmp.so.10
libgmp.so.10.1.2

他们在./configure之外工作：

xena@xena-VirtualBox:~/gnutls$ gedit conftest.c
xena@xena-VirtualBox:~/gnutls$ gcc -o conftest -L"/home/xena/gnutls/out/x86/lib/"   conftest.c -lgmp
xena@xena-VirtualBox:~/gnutls$ ls | grep conftest
conftest
conftest.c
xena@xena-VirtualBox:~/gnutls$ rm conftest
xena@xena-VirtualBox:~/gnutls$ gedit conftest.c
xena@xena-VirtualBox:~/gnutls$ arm-none-linux-gnueabi-gcc -o conftest -L"/home/xena/gnutls/out/arm/lib/" -mcpu=arm926ej-s -mthumb   conftest.c -lgmp
xena@xena-VirtualBox:~/gnutls$ ls | grep conftest
conftest
conftest.c
xena@xena-VirtualBox:~/gnutls$ rm conftest

这是我的构建环境：

xena@xena-VirtualBox:~/gnutls$ pwd
/home/xena/gnutls
xena@xena-VirtualBox:~/gnutls$ ls
build.sh  clean.sh  gmp-5.1.2.tar.xz  gmp-help.txt  gnutls-3.2.2.tar.xz  gnutls-help.txt  nettle-2.7.1.tar.gz  nettle-help.txt

还有我的构建脚本：

ROOT=/home/xena/gnutls

mkdir -p $ROOT/out

tar -xf gmp-5.1.2.tar.xz; cd gmp-5.1.2/
./configure --prefix=$ROOT/out/x86 && make && make install
cd ..; mv gmp-5.1.2 gmp-5.1.2.x86

tar -xf gmp-5.1.2.tar.xz; cd gmp-5.1.2/

cd ..; mv gmp-5.1.2 gmp-5.1.2.arm



tar -xf nettle-2.7.1.tar.gz; cd nettle-2.7.1/
./configure --prefix=$ROOT/out/x86 --disable-openssl --enable-shared CFLAGS="-L\"$ROOT/out/x86/lib/\"" && make && make install
cd ..; mv nettle-2.7.1 nettle-2.7.1.x86

./configure --prefix=$ROOT/out/arm --disable-openssl --enable-shared --host=arm-none-linux-gnueabi CFLAGS="-L\"$ROOT/out/arm/lib/\" -mcpu=arm926ej-s -mthumb" && make && make install
cd ..; mv nettle-2.7.1 nettle-2.7.1.arm



#tar -xf gnutls-3.2.2.tar.xz; cd gnutls-3.2.2/
#./configure --prefix=$ROOT/gnutls-out/x86 --enable-threads=posix --with-sysroot=$ROOT/out/x86 && make && make install
#cd ..; mv gnutls-3.2.2 gnutls-3.2.2.x86

#tar -xf gnutls-3.2.2.tar.xz; cd gnutls-3.2.2/

#cd ..; mv gnutls-3.2.2 gnutls-3.2.2.arm

试试下面的命令，它会起作用。为你的 arm 构建的 gmp 库和包含文件提供正确的路径。

tar -xf nettle-2.7.1.tar.gz; cd nettle-2.7.1/

CFLAGS=-L/$ROOT/out/arm CPPFLAGS=-I/$ROOT/out/arm/include LDFLAGS=-L$ROOT/out/arm/lib ./configure --prefix=$ROOT/out/arm --disable-openssl --enable-shared --host=arm-none-linux-gnueabi

就像你的情况一样，它试图找到链接 gmp。所以 LDFLAGS 将链接您的库文件。

要了解有关如何编译的更多信息，您可以尝试以下命令。它显示了您的配置的一些亮点。

./configure --help

在这里你可以看到各种编译选项。

Fine tuning of the installation directories:

这可以微调您的包。

System types:

在此选项下，它将显示您可以为哪台机器或架构构建和编译。

所以我想我会为您提供最终为我完成的脚本（它基于 vinay hunachyal'a 答案）。它为 x86 和 ARM (i.MX25) 构建具有所有依赖项（两个必需的 + zlib）的 gnutls。

请注意，它不会进行错误检查，因此开箱即用是不安全的。但它有利于参考。
