О чём код?
DJGPP is a software development suite for Intel i386 PCs running DOS operating systems. Compiled binaries for DJGPP by gcc can be run on FreeDOS system. https://www.delorie.com/djgpp/ https://www.freedos.org/ DJGPP port of pciutils supports only direct hardware access methods. Currently available methods are: intel-conf1, intel-conf2 and ecam. More details about particular access method and caveats are described in the pcilib(8) manual page. Method ecam can access PCI Express registers. To compile this port, run following command: make CROSS_COMPILE=i386-pc-msdosdjgpp- HOST=i386-djgpp DNS=no ZLIB=no IDSDIR="" COMPAT_GETOPT=yes This will produce statically linked pcituils exe binaries and static libpci.a library. Building of dynamic shared library is not supported. Ensure that i386-pc-msdosdjgpp-gcc cross compiler is in the PATH env. For optimizing executable sizes, following make options may be useful: OPT="-Os -fomit-frame-pointer -ffunction-sections -fdata-sections" LDFLAGS="-Os -fomit-frame-pointer -s -Wl,--gc-sections" Please note that for running these pciutils executables (like for any other DJPP binaries) it is needed to have installed DPMI server software on target system. The preferred one by DJGPP project is CWSDPMI but any other should work too (e.g. Windows-integrated or HX DPMI). CWSDPMI project is at address: https://sandmann.dotster.com/cwsdpmi/ Pre-built DJGPP pcituils binaries are available at: https://mj.ucw.cz/download/linux/pci/windows/
