我有一個奇怪的問題,libgdal和ECW,在centos 6.5最後。當我嘗試使用gdalinfo(或其他)讀取ECW文件時,出現分段錯誤。Centos 6.5 Final GDAL/ECW分割錯誤
這很奇怪,因爲我有很多具有相同centos和相同ecw/gdal編譯lib的虛擬機,但是這隻發生在其中一個虛擬機上。
試圖用GDB進行調試錯誤,我注意到,ECW試圖分配的2147483647個字符的字符串,但系統上的限制是1073741820.
這是不可能性告訴libgdal/libecw這max_size個限制字符串他們必須使用?有可能改變系統的max_size?
任何想法,將不勝感激:)
OS:的CentOS 6.5(最終) ECW lib目錄下:libecwj2-3.3 GDAL lib目錄下:@中1.9.2
使用gdalinfo打開ecw文件時出錯:

我們也遇到過這個問題。 Libecw會將prefs文件保存在'$ HOME'目錄中。在我們的GDAL環境中取消設置'$ HOME'解決了這個問題。 –
