  1. oops ... did not see that i downloaded energia-1.6.10E18 and it has the issue (appears to be the latest release) ... using win7-64 after doing research on the web for a couple of hours, i determined that the minus sign was causing the issue i started this post because of the package_index.json being signed it appears that the package_index.json.sig file is generated using gpg and a private key (as per this: https://github.com/arduino/Arduino/pull/4457 ) so is there any way to get an updated package_index.json and package_index.json.sig file to go with it ? changing only the boards.txt file causes the following: (plus a bunch of other warnings) E:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\energia\msp430\cores\msp430\atof.c:71:9: warning: floating constant exceeds range of 'double' [-Woverflow] i think that i may be misunderstanding something .... one thing has crossed my mind ... am i on the correct forum for issues with energia-1.6.10E18 ?? js:)
  2. here is one of the g++ command lines that gets generated by the energia ide during compilation problem macro name is highlighted in red "E:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\tools\msp430/bin/msp430-g++" -c -g -O2 -Wall -Wextra -fno-exceptions -ffunction-sections -fdata-sections -fno-threadsafe-statics -MMD -mmcu=msp430f5529 -DF_CPU=16000000L -DARDUINO=10610 -DENERGIA=10610 -DENERGIA_MSP-EXP430F5529LP -DENERGIA_ARCH_MSP430 -IE:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\tools\msp430/include "-IE:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\energia\msp430\cores\msp430" "-IE:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\energia\msp430\variants\MSP-EXP430F5529LP" "E:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\energia\msp430\cores\msp430\main.cpp" -o "C:\Users\xyzabc\AppData\Local\Temp\buildeb17497b6d4359d468573c64f3baa640.tmp\core\main.cpp.o" it causes this warning ( it can be misleading to beginners ) <command-line>:0:12: warning: missing whitespace after the macro name [enabled by default] making the changes to following two files, while the energia ide is open, clears up the issue because it changes the minus sign in the macro name to an underscore ------------------------------------------------------------------------------------------------------------------------------------------------------------ first file E:\programming\MSP430_launchpad\energia-1.6.10E18\hardware\energia\msp430\boards.txt change made #MSP-EXP430F5529LP.build.board=MSP-EXP430F5529LP # macro name contains a minus sign (causes the warning) (comment out line) MSP-EXP430F5529LP.build.board=MSP_EXP430F5529LP # use an underscore instead (add this line) ------------------------------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------------------------------ second file E:\programming\MSP430_launchpad\energia-1.6.10E18\dist\package_index.json change made "boards": [ {"name": "MSP-EXP430F5529LP"}, {"name": "MSP_EXP430F5529LP"}, ........... add this line ( do not include the dots or any of this comment ) {"name": "MSP-EXP430FR4133"}, {"name": "MSP-EXP430FR5969"}, {"name": "MSP-EXP430FR6989"}, {"name": "MSP-EXP430G2"} ], ------------------------------------------------------------------------------------------------------------------------------------------------------------ problem is that when energia ide is restarted, package_index.json file signature verification fails. please consider making changes to all the board names thank you
