Linux 无法将PostgreSQL与OpenSSL交叉编译，在<；openssl/opensslconf.h>；未找到-尽管指定了包含搜索路径

我试图在x86主机上为AArch64目标交叉编译PostgreSQL，并希望使用OpenSSL支持进行编译

我已经使用以下参数成功地为AArch64交叉编译了OpenSSL：

../Configure linux-aarch64 --prefix=$(pwd)/packaged no-dso --cross-compile-prefix="/usr/bin/aarch64-linux-gnu-"
make -j$(nproc)
make -j$(nproc) install

现在开始交叉编译PostgreSQL，我使用以下构建脚本：

test -e postgresql-12.2.tar.gz || wget https://ftp.postgresql.org/pub/source/v12.2/postgresql-12.2.tar.gz
test -e postgresql-12.2 || tar -xzvf postgresql-12.2.tar.gz
cd postgresql-12.2
test -e build_aarch64 && rm -rf build_aarch64
mkdir build_aarch64
cd build_aarch64
../configure --host=aarch64-linux-gnu --without-readline --without-zlib CFLAGS="-O3 -fPIC" CXXFLAGS="-fPIC" CPPFLAGS="-fPIC" --prefix=$PWD/packaged USE_DEV_URANDOM=1 --with-openssl --with-libraries=../../openssl-OpenSSL_1_1_1k/build_aarch64/packaged/lib/ --with-includes=../../openssl-OpenSSL_1_1_1k/build_aarch64/packaged/include/
make -j$(nproc)

configure命令的输出显示include目录已正确设置：

configure: using CPPFLAGS=-fPIC -D_GNU_SOURCE  -I../../openssl-OpenSSL_1_1_1k/build_aarch64/packaged/include/
configure: using LDFLAGS=  -L../../openssl-OpenSSL_1_1_1k/build_aarch64/packaged/lib/

在以下情况下运行

make

命令失败：

/usr/include/openssl/e_os2.h:13:11: fatal error: openssl/opensslconf.h: No such file or directory
   13 | # include <openssl/opensslconf.h>

---

所以文件肯定在include路径中。这是虫子吗？我做得不对吗？

弄明白了，似乎我必须使用绝对路径而不是相对路径来搜索目录：

../configure --host=aarch64-linux-gnu --without-readline --without-zlib CFLAGS="-O3 -fPIC" CXXFLAGS="-fPIC" CPPFLAGS="-fPIC" --prefix=$PWD/packaged USE_DEV_URANDOM=1 --with-openssl --with-libraries=$(pwd)/../../openssl-OpenSSL_1_1_1k/build_aarch64/packaged/lib/ --with-includes=$(pwd)/../../openssl-OpenSSL_1_1_1k/build_aarch64/packaged/include/

---

因此，基本上只是在搜索目录路径的开头添加了

$（pwd）/

。

/usr/include/openssl/e_os2.h:13:11：致命错误：openssl/opensslconf.h:

该错误消息（即

路径

）表明

make

正在查看构建系统

/usr

，不在你的交叉编译环境中？我甚至没听清楚，谢谢@tink
