[英]C++ static cross-compilation failing on LibCurl and OpenSSL
I have a C++ application which depends on both Libcurl (nghttp2 for HTTP/2.0) and OpenSSL to work. 我有一个C ++应用程序,它同时依赖Libcurl(对于HTTP / 2.0为nghttp2)和OpenSSL均可工作。 However, since I don't want any DLL-dependencies I would like to build my application statically (I have the static libraries). 但是,由于我不希望任何DLL依赖关系,因此我想静态地构建应用程序(我有静态库)。 However, I can't get it to work with the underneath command which is cross-compiling from 64-bit Linux for 32-bit Windows, resulting in the errors shown below: 但是,我无法将其与从32位Windows的64位Linux交叉编译的底层命令一起使用,导致出现以下错误:
The Build command: 生成命令:
i686-w64-mingw32-g++ -Wall Programm.cpp -o Programm.exe -I/opt/mingw64/Win32/include -L/opt/mingw64/Win32/lib -I/Software -I/Software/Deps -lcurl -static-libgcc -static-libstdc++ -lcrypto -lssl -lws2_32 -std=c++11 -static -DCURL_STATICLIB
results in these errors: 导致以下错误:
[REMOVED BECAUSE OF TO LARGE BODY] [因身体大而被删除]
UPDATE 更新
I have modified my build command to: 我已将构建命令修改为:
i686-w64-mingw32-g++ -Wall Programm.cpp -o Programm.exe -I/opt/mingw64/Win32/include -L/Software -I/Software/Deps -static-libgcc -static-libstdc++ -lcurl -lnghttp2 -lssl -lcrypto -DCURL_STATICLIB -lpthread -lws2_32 -std=c++11 -static
This leads to the following errors: 这导致以下错误:

You have a few link-order errors. 您有一些链接顺序错误。 The C and C++ linkers are greedy when using static libraries. 使用静态库时,C和C ++链接器贪婪。 If they don't need a symbol by the time they see it, they prune it away. 如果他们在看到符号时不需要符号,则将其修剪掉。 This means you have to be somewhat careful about the order you specify libraries on the command-line. 这意味着您必须对在命令行上指定库的顺序有所注意。 You need to put the consumer .a first, and the supplier .a after. 您需要先将消费者.a放在后面,然后将供应商.a放在后面。
So, in the section of errors like: 因此,在错误部分中,例如:
/opt/mingw64/Win32/lib/libssl.a(ssl_lib.o):ssl_lib.c:(.text+0x6da): undefined reference to `COMP_CTX_free'
/opt/mingw64/Win32/lib/libssl.a(ssl_lib.o):ssl_lib.c:(.text+0x6f2): undefined reference to `COMP_CTX_free'
...
These come because libcrypto was encountered before libssl (which depends on it). 这些是因为libcrypto在libssl之前遇到过(取决于它)。 You can eliminate these by moving -lssl
before -lcrypto
. 您可以通过将-lssl
移至-lssl
之前来消除这些-lcrypto
。
For the ones like 对于像
/opt/mingw64/Win32/lib/libcurl.a(libcurl_la-asyn-thread.o):asyn-thread.c:(.text+0x11): undefined reference to `pthread_mutex_destroy'
/opt/mingw64/Win32/lib/libcurl.a(libcurl_la-asyn-thread.o):asyn-thread.c:(.text+0xb8): undefined reference to `pthread_mutex_lock'
Your libcurl is looking for libpthread, so you need to put -lpthread
after -lcurl. 您的libcurl正在寻找libpthread,因此您需要将-lpthread
放在-lcurl 之后 。 It looks like libcurl is also looking for an ldap implementation...I'm not really familliar with that, but there's probably a -lldap
missing somewhere (presuming libldap). 似乎libcurl也在寻找ldap实现...我对此并不陌生,但是-lldap
可能在-lldap
缺失(假设是libldap)。 Lastly, I don't see your nghttp
library anywhere on the command-line. 最后,在命令行上的任何地方都看不到您的nghttp
库。 It looks like it should follow -lcurl
as well. 看起来它也应该遵循-lcurl
。
That leaves the missing libcurl imports at the top; 这将缺少的libcurl导入放在顶部; I don't have any idea there. 我在那里没有任何想法。
