Hi, I have installed the Wine from winehq.com from the source Wine installed properly. But I am trying to do a make in my Libixprouter/ue/src. make does not complain about anything, except something in the .sed file. (Please refer log below). But there is no microcode in the microcode array as expected. For eg when I do "touch xmt.uc" and do a make, I expect the microcode in the xmt.x file but the xmt_uCodeArr[] array in xmt.x is empty. Can someone point out what is going wrong ? I can give more details. Thank you. Jagan. The output from make (collected as $make &> /tmp/make_out) after a touch xmt.uc is as follows. /* start of make - added by me */ -- preprocessing xmt -- For language 'english' several language ids were found: en_US - 0409; en_GB - 0809; en_AU - 0C09; en_CA - 1009; en_NZ - 1409; en_IE - 1809; en_ZA - 1C09; en_JM - 2009; en_ - 2409; en _BZ - 2809; en_TT - 2C09; Instead of using first in the list, suggest to define your LANG environment variable like this: LANG=en_US Assembly successful.^M -- allocating registers for xmt -- -- creating xmt.uca -- sed: file xmt.sed line 5: Invalid reference \2 on `s' command's RHS -- assembling xmt -- For language 'english' several language ids were found: en_US - 0409; en_GB - 0809; en_AU - 0C09; en_CA - 1009; en_NZ - 1409; en_IE - 1809; en_ZA - 1C09; en_JM - 2009; en_ - 2409; en _BZ - 2809; en_TT - 2C09; Instead of using first in the list, suggest to define your LANG environment variable like this: LANG=en_US Preprocessing successful; output file, "xmt.uci" written.^M ^M ^M Reading "xmt.uci": pass 1...^M Reading "xmt.uci": pass 2...^M ^M Number of uwords compiled: 0^M Number of pages compiled: 1^M Ucode output written to: "xmt.list"^M Assembly successful.^M -- extracting xmt -- perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_CTYPE = "", LANG = "english" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). rm xmt.sed /* end of make - added by me */
