Building with make

TLDR

make
make install

Build instructions

To build flashrom you need to install the following software:

  • C compiler (GCC / clang)
  • pkg-config
  • pciutils+libpci (if you want support for mainboard or PCI device flashing)
  • libusb (if you want FT2232, Dediprog or USB-Blaster support)
  • libftdi (if you want FT2232 or USB-Blaster support)
  • libjaylink (if you want support for SEGGER J-Link and compatible devices)
  • NI-845x driver & library package (if you want support for NI-845x devices; uses a proprietary driver)

Linux et al:

  • pciutils / libpci
  • pciutils-devel / pciutils-dev / libpci-dev
  • zlib-devel / zlib1g-dev (needed if libpci was compiled with libz support)

On FreeBSD, you need the following ports:

  • devel/gmake
  • devel/libpci

On OpenBSD, you need the following ports:

  • devel/gmake
  • sysutils/pciutils

To compile on Linux, use:

make

To compile on FreeBSD, OpenBSD or DragonFly BSD, use:

gmake

To compile on Nexenta, use:

make

To compile on Solaris, use:

gmake LDFLAGS="-L$pathtolibpci" CC="gcc -I$pathtopciheaders" CFLAGS=-O2

To compile on NetBSD (with pciutils, libftdi, libusb installed in /usr/pkg/), use:

gmake

To compile and run on Darwin/Mac OS X:

Install DirectHW from coresystems GmbH. DirectHW is available at https://www.coreboot.org/DirectHW .

To compile on Windows:

Install MSYS tools (and the NI-845x drivers if desired) as described in Installing dependencies.

To build with support for NI-845x:

make HAS_LIB_NI845X=yes CONFIG_NI845X_SPI=yes

To cross-compile on Linux for DOS:

Get packages of the DJGPP cross compiler and install them:

  • djgpp-filesystem djgpp-gcc djgpp-cpp djgpp-runtime djgpp-binutils

As an alternative, the DJGPP web site offers packages for download as well:

  • djcross-binutils-2.29.1-1ap.x86_64.rpm
  • djcross-gcc-7.2.0-1ap.x86_64.rpm
  • djcrx-2.05-5.x86_64.rpm

The cross toolchain packages for your distribution may have slightly different names (look for packages named djgpp).

Alternatively, you could use a script to build it from scratch: https://github.com/andrewwutw/build-djgpp

You will need the libpci and libgetopt library source trees and their compiled static libraries and header files installed in some directory say libpci-libgetopt/, which will be later specified with LIBS_BASE parameter during flashrom compilation. Easiest way to handle it is to put pciutils, libgetopt and flashrom directories in one subdirectory. There will be an extra subdirectory libpci-libgetopt created, which will contain compiled libpci and libgetopt.

Download pciutils 3.5.6 and apply https://flashrom.org/File:Pciutils-3.5.6.patch.gz Compile pciutils, using following command line:

make ZLIB=no DNS=no HOST=i386-djgpp-djgpp CROSS_COMPILE=i586-pc-msdosdjgpp- \
        PREFIX=/ DESTDIR=$PWD/../libpci-libgetopt  \
        STRIP="--strip-program=i586-pc-msdosdjgpp-strip -s" install install-lib

Download and compile with ‘make’ https://flashrom.org/File:Libgetopt.tar.gz

Copy the libgetopt.a to ../libpci-libgetopt/lib and getopt.h to ../libpci-libgetopt/include

Enter the flashrom directory:

make CC=i586-pc-msdosdjgpp-gcc STRIP=i586-pc-msdosdjgpp-strip LIBS_BASE=../libpci-libgetopt/ strip

If you like, you can compress the resulting executable with UPX:

upx -9 flashrom.exe

To run flashrom.exe, download https://flashrom.org/File:Csdpmi7b.zip and unpack CWSDPMI.EXE into the current directory or one in PATH.

To cross-compile on Linux for Windows:

Get packages of the MinGW cross compiler and install them:

mingw32-filesystem mingw32-cross-cpp mingw32-cross-binutils mingw32-cross-gcc
mingw32-runtime mingw32-headers

The cross toolchain packages for your distribution may have slightly different names (look for packages named mingw). PCI-based programmers (internal etc.) are not supported on Windows. Run (change CC= and STRIP= settings where appropriate):

make CC=i686-w64-mingw32-gcc STRIP=i686-w64-mingw32-strip

Processor architecture dependent features:

On non-x86 architectures a few programmers don’t work (yet) because they use port-based I/O which is not directly available on non-x86. Those programmers will be disabled automatically if you run “make”.

Compiler quirks:

If you are using clang and if you want to enable only one driver, you may hit an overzealous compiler warning from clang. Compile with “make WARNERROR=no” to force it to continue and enjoy.

Bindings:

Foreign function interface bindings for the rust language are included in the bindings folder. These are not compiled as part of the normal build process. See the readme under bindings/rust for more information.

Installation

In order to install flashrom and the manpage into /usr/local, type:

make install

For installation in a different directory use DESTDIR, e.g. like this:

make DESTDIR=/usr install

If you have insufficient permissions for the destination directory, use sudo by adding sudo in front of the commands above.

Packaging

To package flashrom and remove dependencies on Git, either use:

make export

or:

make tarball

make export will export all flashrom files from the Git repository at revision HEAD into a directory named $EXPORTDIR/flashrom-$RELEASENAME and will additionally add a versioninfo.inc file in that directory to contain the Git revision of the exported tree and a date for the manual page.

make tarball will simply tar up the result of make export and compress it with bzip2.

The snapshot tarballs are the result of make tarball and require no further processing. Some git files (for example the rust bindings) are omitted from the tarball, as controlled by the .gitattributes files.
