problem with winsock2.h and configure ? #17

Closed sebi008 closed 12 years ago

sebi008 commented 12 years ago

the command ./configure send me a warning telling me to come here and report what's happened: " configure: WARNING: winsock2.h: present but cannot be compiled configure: WARNING: winsock2.h: check for missing prerequisite headers? configure: WARNING: winsock2.h: see the Autoconf documentation configure: WARNING: winsock2.h: section "Present But Cannot Be Compiled" configure: WARNING: winsock2.h: proceeding with the compiler's result configure: WARNING: ## ----------------------------------------------------------- ## configure: WARNING: ## Report this to https://github.com/stephane/libmodbus/issues ## configure: WARNING: ## ----------------------------------------------------------- ## "

Which version?

sebi008 commented 12 years ago

I'm on windows XP pro SP3; using cygwin 2.738 I've download "stephane-libmodbus-v3.0.0-0-g00cb49e.zip"

after the finish of configure with "no" error (nothing is written on the screen) the execution of make command tell me :

make all-recursive make[1]: Entering directory /home/solivier/liibmodbus' Making all in src make[2]: Entering directory/home/solivier/liibmodbus/src' if /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFI u.Tpo" -c -o modbus-rtu.lo modbus-rtu.c; \ then mv -f ".deps/modbus-rtu.Tpo" ".deps/modbus-rtu.Pl libtool: compile: gcc -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 -Wa ORT -DPIC -o .libs/modbus-rtu.o modbus-rtu.c:36:26: error: linux/serial.h: No such file or dir modbus-rtu.c: In function 'modbus_rtu_set_serial_mode': modbus-rtu.c:713: error: storage size of 'rs485conf' isn't kno modbus-rtu.c:714: error: invalid application of 'sizeof' to in modbus-rtu.c:717: error: 'SER_RS485_ENABLED' undeclared (first modbus-rtu.c:717: error: (Each undeclared identifier is report modbus-rtu.c:717: error: for each function it appears in.) modbus-rtu.c:718: error: 'TIOCSRS485' undeclared (first use in cc1: warnings being treated as errors modbus-rtu.c:713: error: unused variable 'rs485conf' make[2]: * [modbus-rtu.lo] Error 1 make[2]: Leaving directory `/home/solivier/liibmodbus/src' make[1]: * [all-recursive] Error 1 make[1]: Leaving directory`/home/solivier/liibmodbus' make: *\ [all] Error 2

I can't copy all the screen to paste here so the commands are truncated. I'm sorry this is my first use of cygwin. thank you

OK, I've merged some fixes for Windows for the v3.0.1 Can you test again with https://github.com/stephane/libmodbus/zipball/v3.0.1 ?

I have the same warning but the make command give me another thing with this version :

It's useless to post so many lines for just this error, you just have an issue with xmlto or your asciidoc installation. The libmodbus is designed to be compiled under mingw not cygwin.

Your initial problem is fixed (winsock2.h error) so the but must be closed. Feel free to submit patch for Cygwin, but please don't submit bug report for this environment, I won't take time to support it.

sebi008 commented 12 years ago

thank you for your response . I'm sorry to flooded you but since i'm not the original creator of the library i can't know what thing can be important to have to debug. and for cygwin i never saw that the library was designed only for mingw . with the previous release cygwin and mingw had the same results and i thought it was the same with this version. It can be good for beginners to write it in the readme.rst and to avoid you wasting time for nothing. I will use mingw : it appears to be OK.
