From b65cc5d50414212efa0029e7715c92e880967a4f Mon Sep 17 00:00:00 2001 From: Even Rouault Date: Thu, 27 Sep 2018 19:15:13 +0200 Subject: cs2cs_emulation_setup: fix issue with non C-locale in +towgs84 case, we use sprintf() with floating-point formatter to output the ellipsoid parameters. For a locale with decimal separtor != dot, the resulting string will not be parsed correctly by proj_atof(), leading to wrong numeric result. The fix is similar to the one done in pj_latlong_from_proj() Note for later: if using C++, we could use a locale-independent formatting solution to avoid such issue. --- src/pj_utils.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/pj_utils.c') diff --git a/src/pj_utils.c b/src/pj_utils.c index 3f18cc7e..81a80b45 100644 --- a/src/pj_utils.c +++ b/src/pj_utils.c @@ -105,6 +105,8 @@ PJ *pj_latlong_from_proj( PJ *pj_in ) { char* ptr = defn+strlen(defn); sprintf( ptr, " +es=%.16g", pj_in->es ); + /* TODO later: use C++ ostringstream with imbue(std::locale::classic()) */ + /* to be locale unaware */ for(; *ptr; ptr++) { if( *ptr == ',' ) -- cgit v1.2.3
