Built cscope from 15.3 source files in Cygwin Bash shell (cygwin1.dll version 1003.10.0.0 and cygncurses6.dll), using the following commands: ./configure make make install I then copied the cscope.exe file to a Windows 2000 SP 2 system (with the cygwin1.dll version 1003.10.0.0 and cygncurses6.dll on the system and their location added to the Windows PATH variable). I created a file named "cscope_files" that has a list of relative paths (from the root of the drive I am running cscope from) to all of the .c, .cpp, and .h files that are part of the build. There are 1722 files in the build in various directories. I then entered the following command in the MS-DOS shell window: T:\clark>cscope -bqu -f t:\clark\cscope.out -i t:\clark\cscope_files and I got the following: cscope: cannot open file t:\clark\cscope.out I then tried the following command (used forward slashes instead of backslashes): T:\clark>cscope -bqu -f cscope.out -f cscope_files and I got the following cscope: no source files found I then tried the following command (used forward slashes instead of backslashes): T:\clark>cscope -bqu -f t:/clark/cscope.out -i t:/clark/cscope_files and I got the following: cscope: cannot create inverted index; ignoring -q option cscope: removed files t:/clark/ncscope.out.in and t:/clark/ncscope.out.po Question: why is cscope doing more when I give it file paths with forward slashes when the Windows shell use backslashes? I then tried invoking cscope and pass it the locatations of the cscope.out and cscope_files files: T:\clark>cscope -f cscope.out -i cscope_files Cscope the displayed the text screen and says "Building symbol database". After it is finished building the database, it displays "Press the RETURN key to continue:" I pressed the "Enter" key and the cursor appears in the middle of the line "Find this global definition:". It looks like the initial cursor position in down one more line than it should be. I then enter the name of a data type in the "Find this C symbol:" and I get the following output: Cscope version 15.3 Press the ? key for help C symbol: uint8_t File Function Line 0 \draco_01 \mech\src\cbio\cbio_acumen.cpp <global> 36 uint8_t page_mode_write_ok = 0;1 \draco_01 \mech\src\cbio\cbio_acumen.cpp <gl obal> 38 uint8_t page_mode_write_ok = 1;2 \draco_01\mech\src\c bio\cbio_acumen.cpp <global> 41 uint8_t page_m ode_read_ok = 0;3 \draco_01 \mech\src\cbio\cbio_acumen.cpp <global> 43 uint8_t page_mode_read_ok = 1;4 \draco_01\mech\src\cbio\cbio_acumen.cpp <global> 324 uint8_t *result)5 \draco_01\mech\src\c bio\cbio_acumen.cpp <global> 432 uint8_t *srcPt r)6 \draco_01 \mech\src\cbio\cbio_acumen.cpp <global> 573 uint8_t *destPtr)7 \draco_01 \mech\src\cbio\cbio_acumen.cpp <global> 711 uint8_t *srcPtr)8 \draco_01\mech\src\cbio\cbio_acumen.cpp <global> 842 uint8_t9 \draco_01\mech\src\cbio\cbio_acu men.cpp <global> 846 static uint8_t acumenByte; a \draco_01 \mech\src\cbio\cbio_adc.cpp <global> 102 uint8_t controller_channel;b \draco_01 \mech\src\cbio\cbio_adc.cpp <global > 103 uint8_t adc_mux;c \draco_01\mech\src\cbio\cbio_adc.cpp <global> 668 uint8_t mux[CBIO_MAX_CONTROLLER_C HANNELS];d \draco_01 \mech\src\cbio\cbio_adc.cpp <global> 899 uint8_t offsetDacValue [ENDEV_NUM_CHANNELS] = {e \draco_01 \mech\src\cbio\cbio_adc.cp p <global> 971 STATIC uint8_t iDefaultEndevA DCMuxCh = cbioChannelMapTable [CBIO_CHAN_ENDEV_DEFAULT].mux[0];f \draco_01 \mech\src\cbio\cbio_adc.cpp <global> 988 uint8_t iMux,g \draco_01\mech\ src\cbio\cbio_adc.cpp <global> 1000 STATIC vo id SetSynergyADCMux( cbioController_t, uint8_t, boolean_t );h \draco_01\mech\src\cbio\cbio_gbl.h <global> 212 uint8_t bDisplayToConsole = 0;i \draco_01 \mech\src\cbio\cbio_gbl.h <global> 213 uint8_t bDisplayToUDW = 1;j \draco_01 \mech\src\cbio\cbio_gbl.h <global> 214 uint8_t bUDWThread = 0;k \draco_01\mech\src\cbio\cbio_gbl.h <global> 215 uint8_t bOutputToFile = 0;l \ draco_01 \mech\src\cbio\cbio_gbl.h <global> 220 extern uint8_t bDisplayToConsole;m \draco_01 \mech\src\cbio\cbio_gbl.h <glo bal> 221 extern uint8_t bDisplayToUDW;n \draco_01\mech\src\cbio \cbio_gbl.h <global> 222 extern uint8_t bU DWThread;o \draco_01 \mech\src\cbio\cbio_gbl.h <global> 223 extern uint8_t bOutputToFile;p \draco_01\mech\src\cbio\cbio_gpio.cpp Find<global>symbol: 189 uint8_t reg[CBIO_NUM_CONT_TYPES];q \draco_01\m Find this global def Find functions called by this function: Find functions calling this function: Find this text string: Change this text string: Find this egrep pattern: Find this file: Find files #including this file: If I press a number key, then a file is loaded into less.exe (I have the VIEWER variable set to less.exe) just fine.

As you can see in the above examples, cscope 15.3 prints the entire path that was extracted from the cscope_files file. It would easier on the user to just see the file name and its parent directory, which should work with the "-p 2" option. When I entered the following command: T:\clark>cscope -p 2 -f cscope.out -i cscope_files and I then searched for files that #include "intLib.h", all of the file paths listed in the "File" column are displayed as the entire file path, not just the last two path components (file name and parent directory). I do not have these problems on version 12.9 of cscope on my HP-UX 10.20 workstation (I don't know how relevant this is as I do not know where this cscope sources came from). Did I not build the cscope 15.3 files correctly with Cygwin or is this just the general behavior of cscope on a Windows 2000 system? To summarize my questions: 1) Why does cscope in a Windows command shell prefer forward slashes instead of backslashes? 2) When I pass entire file paths for cscope.out and cscope_files to cscope, it says it cannot open the cscope.out file. But when I invoke cscope and just pass it the filenames "cscope.out" and "cscope_files" without the paths, it then runs and builds a database. 3) How comew sometimes the list of files that a search term is found is all messed up on the screen and othertimes the list is not messed up? 4) The -p option seems to have no effect on the list of files a search term is in. 5) Is there some special configuration I should be building the cscope 15.3 source file with Cygwin or for use on a Windows 2000 system? Attached is the cscope.exe binary built with Cygwin on a Windows 2000 system. Requires the Cygwin cygwin1.dll and cygncurses6.dll files.
