Do you use libcurl for Android development a lot?

Curl is a well-known open-source file transfer protocol implementation software, which includes the implementation of many common and uncommon protocols such as HTTP, HTTPS, FTP, etc. In the latest version of curl, the official source ** actually includes the android build file (, but there is still some work to be done to compile it. The curl version I'm using is 7

libcurl is a network library developed in C that supports a variety of network protocols.

There are many different ways to compile the C language**. This uses the compilation method under the UNIX platform. Even if you're using a different operating system, you can still get a lot of useful information by reading this document.

Compiling your compiler must know the location of the libcurl header file. So at compile time, you need to set the path to include the header file. You can use the curl-config tool to get this information:

curl-config –cflags

After compiling the source code (in this case, the source is not the source of libcurl, you are writing your own program), you must also link the object file into a single executable. You'll want to link the libcurl library, as well as other libraries that libcurl depends on, such as the opensll library. Of course, some other operating system libraries may be required.

Finally, you need to set some compilation options, which can be simplified by using the curl-config tool

curl-config –libs

Whether to use SSL

Custom compilation libcurl. Unlike other libraries, libcurl can be custom compiled to support certain features such as SSL transport, such as HTTPS and FTPS, depending on the actual needs. If you decide that you need to support SSL, you must set it up correctly at compile time.

You can use curl-config to tell if the libcurl library supports ssl:

curl-config –feature

Works as lib on properties-> android is library.

Use lib's project properties->android and click add to add the above project.

When you access https, you mean the server certificate (SSL certificate), right? You don't have to develop this yourself.,Just apply for a free one.,The compatibility and stability of the web link is better.。

Open coredump to get the core file, and use gdb to analyze the core file.

How do you compile, cocos2dx can't be compiled directly, to compile the main project includes compilation. You can refer to the tests file and turn a few environment variables into your own path before running it. The jni directory of your main project and also refer to the corresponding files in tests, which are mainly to add the dependencies of cocos2d-x projects.

curl offt t t multiple definitions. It's obviously a problem with curl, i.e. a problem with the configurable argument. You see if it is caused by the introduction of unnecessary header files, detailed information should be there.

Compile your own library under the Android system, it's not called cross-compilation.,Hehe.。 Please post the steps, error message.

All data, contacts, text messages, notes, and other data that cannot be cleared can be deleted on your phone and wait for the sync.

This answer comes from the official Meizu MX2**.

Has anyone successfully compiled it?,Post the complete information?,I'm running into this problem now.。

After configue passed, I got an error when making : home fedora android:148:

error: conflicting types for 'curl_off_t'/home/fedora/android/:172:

error: previous declaration of 'curl_off_t' was herein file included from :75:

Excuse me, everybody. What's going on?

Five threads.

Handles can be locked separately.

Alternatively, implement an array of handles, with each thread using only the data from its own handle.

Because libcurl itself has a curl variable, using five curls ensures that there are no conflicts.

At present, the frameworks are mainly open source frameworks, which can be found on github:

1. Inner volley, 2. android-async-http

3. Afinal framework.

4. Xutils framework.

6、loonandroid

There are mainly the following modules: capacity.
