$Id: INSTALL,v 1.1.1.1 2004/05/18 01:50:44 kgibbs Exp $
Briefly:
Do one-time if needed, e.g. for systems with dnf
dnf install gcc
dnf install gcc-c++
dnf install make
dnf install automake
then to build do:
./configure -- configure for your machine
make -- compile Iperf
make install -- install Iperf, if desired, from root
and to use:
iperf -s (on machine "foo.bar.edu")
iperf -c foo.bar.edu (on some other machine)
iperf -h (for help screen)
iperf -v (for version information)
Platform Specific Notes
FreeBSD
If you use a cc or c++ other than the system one, threads may not be
detected properly. To work around this set the following environment
variables:
setenv CC /usr/bin/cc
setenv CXX /usr/bin/c++
---
Windows (cross compile from Linux)
# dnf install mingw32-gcc mingw32-gcc-c++ mingw32-winpthreads-static
$ ../iperf2-code/configure --host=i686-w64-mingw32
$ make
---
Windows (Cygwin)
configure / make as normal:
$ ../iperf2-code/configure
$ make
The result requires Cygwin on client machines.
---
Windows (Cygwin + i686-w64-mingw32)
Use Cygwin Setup to install i686-w64-mingw32 and related packages
Configure as a cross-compile:
$ ../iperf2-code/configure -host i686-w64-mingw32
$ make
The result runs natively on WinXP and above without requiring Cygwin
---
Windows (MinGW + Msys)
Install MinGW+Msys
https://sourceforge.net/projects/mingw/
http://www.mingw.org/wiki/MinGW
http://www.mingw.org/wiki/MSYS
configure / make as normal:
$ ../iperf2-code/configure
$ make
The result runs natively on WinXP and above without requiring
MinGW+Msys on client machines.
---
OpenWRT cross compile (example only)
Setup buildroot (not fully described here, link https://electrosome.com/cross-compile-openwrt-c-program/)
determine the target environment from the openwrt banner (this example is openwrt)
get the build environment, e.g. git clone https://github.com/openwrt/openwrt.git
update feeds
$ ./scripts/feeds update -a
$ ./scripts/feeds install -a
configure target
$ make menuconfig
Then select Target System, Subtarget and Target Profile as per your target environment, e.g.
Target System: MediaTek Ralink MIPS
Subtarget system: MT7620 based boards
Target profile: NETGEAR R6350
Set environment variables (via any editor or manual exports to get)
[rjmcmahon@localhost iperf2-code]$ more ../openwrt.config
export STAGING_DIR=/home/usernmae/Code/openwrt/staging_dir
export TOOLCHAIN_DIR=$STAGING_DIR/toolchain-mipsel_24kc_gcc-8.4.0_musl (this is target dependent)
export LDCFLAGS=$TOOLCHAIN_DIR/usr/lib
export LD_LIBRARY_PATH=$TOOLCHAIN_DIR/usr/lib
export PATH=$TOOLCHAIN_DIR/bin:$PATH
$ source ../openwrt.config
Download iperf 2 source
$ cd iperf2-code
Run configure, e.g. (replace /home/rjmcmahon/Code with your directory)
$ ./configure --target=mips-buildroot-linux-gnu --host=mips-buildroot-linux-gnu CC=/home/rjmcmahon/Code/openwrt/staging_dir/toolchain-mipsel_24kc_gcc-8.4.0_musl/bin/mipsel-openwrt-linux-gcc CXX=/home/rjmcmahon/Code/openwrt/staging_dir/toolchain-mipsel_24kc_gcc-8.4.0_musl/bin/mipsel-openwrt-linux-g++
Cross compile (binary in the src/ directory)
$ make
Install iperf and shared libraries onto openwrt device
ssh into openwrt device, $ opkg install libstdcpp
$ scp src/iperf user@host:/usr/bin
---
Other configure and compile options
./configure --enable-debuginfo - enable asserts
./configure --enable-thread-debug - enable thread level debugging
./configure --enable-summing-debug - enable summing level debugging
./configure --enable-packet-debug - show packet sequence numbers - very chatty
./configure --enable-fastsampling - sub millisecond timestamping
./configure --enable-checkprograms - compile supplmentary test programs
./configure --disable-ipv6
./configure --disable-multicast
./configure --disable-threads
./configure --disable-write-select
./configure --enable-debug-symbols - enable debugging with symbols
./configure --enable-default-localonly - limit test traffic to the local network (off by default)
