Wes McKinney commented on ARROW-584: ------------------------------------ I should add that building with {{-m32}} on Linux exposes many additional warnings on platforms where {{sizeof(int)}} is 4 (like Win32) > [C++] Fix compiler warnings exposed with -Wconversion > ----------------------------------------------------- > > Key: ARROW-584 > URL: https://issues.apache.org/jira/browse/ARROW-584 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Reporter: Wes McKinney > > We have a number of imprecise or implicit integer conversions -- it would be > good to address all of these warnings, and additionally to build with > {{-Wconversion}} in Travis CI so we keep the build clean going forward. > Some of these warnings may so away as part of ARROW-493 but there are many > others. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
