FreeRDP has a few dependencies that are required for proper operation:
|
||
|
|
|
||
|
|
1. SSL
|
||
|
|
|
||
|
|
RDP requires a secure tunnel and utilizes TLS for this. We do not implement this
|
||
|
|
ourselves but reuse existing libraries:
|
||
|
|
|
||
|
|
We support
|
||
|
|
|
||
|
|
* OpenSSL our main development SSL library
|
||
|
|
* LibreSSL (supported by community)
|
||
|
|
* MBedTLS (supported by community)
|
||
|
|
|
||
|
|
2. Kerberos
|
||
|
|
|
||
|
|
Authentication to many services requires kerberos (especially if smartcards are in use)
|
||
|
|
|
||
|
|
We support:
|
||
|
|
|
||
|
|
* MIT
|
||
|
|
* Heimdal
|
||
|
|
|
||
|
|
3. JSON
|
||
|
|
|
||
|
|
Azure logon requires HTTP/JSON messages to be parsed.
|
||
|
|
|
||
|
|
We support:
|
||
|
|
|
||
|
|
* cJSON
|
||
|
|
|
||
|
|
4. H264
|
||
|
|
|
||
|
|
RDP GFX modes (anything newer Windows 8.1 / Server 2012) supports a graphics mode based
|
||
|
|
on the H264 codec
|
||
|
|
|
||
|
|
We support
|
||
|
|
|
||
|
|
* OpenH264
|
||
|
|
* FFMPEG (x264 or OpenH264)
|
||
|
|
|
||
|
|
There are some platform specific implementations too (e.g. mediacodec on android) but these
|
||
|
|
two are the options that are always required.
|
||
|
|
|
||
|
|
5. Graphics scaling support
|
||
|
|
|
||
|
|
High DPI support and smart-sizing option require bitmaps to be scaled by the client.
|
||
|
|
|
||
|
|
We support
|
||
|
|
|
||
|
|
* Swscale
|
||
|
|
* Cairo
|
||
|
|
|
||
|
|
6. Audio encoders/decoders
|
||
|
|
|
||
|
|
Sound and Microphone options allow transmission of data in compressed formats.
|
||
|
|
The most widely supported formats are uncompressed PCM (all systems support that)
|
||
|
|
and compressed AAC (windows 8 or newer). Some other codecs are supported as well (GSM)
|
||
|
|
but do not provide the same quality as the afore mentioned ones.
|
||
|
|
|
||
|
|
We support
|
||
|
|
|
||
|
|
* FAAC / FAAD2 / soxr (encoder/decoder/resampling)
|
||
|
|
* FFMPEG
|
||
|
|
* GSM (older low bandwidth codec)
|
||
|
|
|
||
|
|
7. Smartcard
|
||
|
|
|
||
|
|
To utilize smartcards for authentication/redirection
|
||
|
|
|
||
|
|
We support
|
||
|
|
|
||
|
|
* PCSC
|
||
|
|
* pkcs11
|
||
|
|
|
||
|
|
PCSC is required for smartcard redirection, pkcs11 for NLA smartcard logon support
|
||
|
|
|
||
|
|
8. Unicode
|
||
|
|
|
||
|
|
Most of the protocol preferably uses UCS-2/UTF16 for strings. To convert to/from UTF-8 a
|
||
|
|
unicode support library is required:
|
||
|
|
|
||
|
|
* Windows natively supports these (well, it is a microsoft protocol after all ;))
|
||
|
|
* ICU on linux/unix and android
|
||
|
|
* On Apple (iOS/Mac) we use native NSString unicode conversion routines
|
||
|
|
|
||
|
|
9. USB redirection
|
||
|
|
|
||
|
|
The protocol has an extension (channel) to allow low level USB redirection
|
||
|
|
|
||
|
|
We support
|
||
|
|
|
||
|
|
* libusb 1
|
||
|
|
|
||
|
|
10. Platform support (mainly linux, for others the platform SDK is usually enough)
|
||
|
|
|
||
|
|
* SDL2 for the SDL client (all platforms)
|
||
|
|
* CUPS (linux/apple) for printing support
|
||
|
|
* libsystemd (linux) for journald logging support
|
||
|
|
* PAM headers/libraries (server side authentication)
|
||
|
|
* FUSE/FUSE3 for file clipboard support (linux/mac os)
|
||
|
|
* Wayland for wlfreerdp
|
||
|
|
* X11 development headers for X11 client
|
||
|
|
* ALSA development headers/libraris
|
||
|
|
* PULSE development headers/libraries
|
||
|
|
* OSS development headers/libraries
|
||
|
|
|
||
|
|
11. Building recommendations
|
||
|
|
|
||
|
|
* Use Ninja to speed up your builds
|
||
|
|
* For release builds add -DCMAKE_BUILD_TYPE=Release (or RelWithDebInfo for less optimized but with debug symbols)
|
||
|
|
* -DWITH_VERBOSE_WINPR_ASSERT=OFF reduces the size of the build considerably but removes lots
|
||
|
|
of santity checks in code. Recommended for stable builds, for builds not from stable releases
|
||
|
|
it is recommended to keep -DWITH_VERBOSE_WINPR_ASSERT=ON to have useful information on crashes.
|
||
|
|
|
||
|
|
12. Example build instructions:
|
||
|
|
|
||
|
|
Assume we have the source checked out to /tmp/freerdp/src and we want to install to /tmp/freerdp/install:
|
||
|
|
(on windows this needs to be called from a visual studio command prompt or a cmd that has run vcvarsall.bat, paths obviously need to be adjusted)
|
||
|
|
|
||
|
|
cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DWITH_VERBOSE_WINPR_ASSERT=OFF -DCMAKE_PREFIX_PATH=/tmp/freerdp/install -B /tmp/freerdp/build -S /tmp/freerdp/src
|
||
|
|
cmake --build /tmp/freerdp/build --target install
